    Dynamics in the systems with the 3-spin coupling induced by the strong radiofrequency field / V. E. Zobov, M. A. POPOV // Zhurnal Eksperimentalnoi Teor. Fiz. - 1993. - Vol. 103, Is. 6. - P. 2129-2141. - Cited References: 24 . - ISSN 0044-4510

Аннотация: The dynamics of the crystal nucleus spin system in constant and continuous strong radiofrequency magnetic fields is studied. The variation of the relaxation properties of the magnetization perpendicular to the effective field is studied with changing the field orientation in the rotating frame of coordinates and with changing the relation in the mean hamiltonian of two- and three-spin dipole-dipole couplings. The third and fourth moments of the NMR spectrum in the rotating frame of coordinates and the free precession fall are calculated by means of the memory function. The connection between the three-spin coupling and the features of such falls observed in the experiments under magic angle and bias from it is explained.

    Effect of fluctuations on the NQR spectrum in the incommensurate phase of a Cs2ZnI4 crystal / M. A. Popov, I. P. Aaleksandrova, S. V. Primak // JETP Letters. - 1994. - Vol. 59, Is. 7. - P. 485-487. - Cited References: 5 . - ISSN 0021-3640
РУБ Physics, Multidisciplinary

Аннотация: The direct spin-lattice relaxation due to local thermal fluctuations of the amplitude of the atomic-displacement wave -in the incommensurate phase of a crystal can strongly influence the lineshape of the resonant spectrum, reducing the intensity of the outermost temperature-dependent peaks in the frequency distribution, while having essentially no effect on the temperature-independent features of this distribution. This effect is apparently the reason for the anomalous behavior of the NQR spectrum of I-127 in Cs2ZnI4 in a certain temperature interval near the transition from the ''normal'' phase to the incommensurate phase.

    Вecay of the free precession of nuclear spins in a solid in a rotating coordinate system under magic-angle conditions - 3-spin interactions / A. E. Mefed [et al.] // JETP Letters. - 1992. - Vol. 55, Is. 7. - P. 418-423. - Cited References: 15 . - ISSN 0021-3640

Аннотация: Experiments show that the signal representing the decay of the free precession of nuclear spins of F-19 in a CaF2 crystal decreases in a monotonic fashion, without oscillations, in a rotating coordinate system under magic-angle conditions. The decrease is thus fundamentally different from that in the laboratory coordinate system. When a deviation from the magic angle is introduced, oscillations appear in the precession-decay signal. These oscillations are distinctive in that the signal does not reach zero at the first few minima. These features of the free-precession decay are explained on the basis that the nuclear dipole-dipole interactions in the rotating coordinate system under magic-angle conditions are fundamentally different from those in the laboratory system. Theoretical predictions agree qualitatively with the experimental results.

COPPER METABORATE
Аннотация: Nuclear magnetic resonance (NMR) experiments on copper metaborate CuB2O4 are performed in order to study the successive phase transitions which includes the transition from the paramagnetic to the commensurate weak ferromagnetic phase at T-N = 21 K and further transition to the incommensurate helix phase at T* similar to 10 K. B-11-NMR spectra obtained for three crystal orientations (B parallel to [001], [110], [100]) were split into several lines below T-N and changed into more complicated line shapes below T*. The results of the angular dependence of the spectrum in the commensurate phase and the nuclear spin-lattice relaxation rate T-1(-1) are also discussed.

Аннотация: The results of the experimental study and computer simulation of the resonance spectra of a single crystal of the iron-manganese sulfide FexMn1-xS (0 <=x <=0.29) are presented. The resonance properties of the concentrated solid solutions are explained by the formation of a homogeneous FexMn1-xS matrix with randomly distributed superparamagnetic iron nanoparticles. The mean diameter (< D > = 6.19 nm at T=250 K) and the axial first-order anisotropy constant (K-1 = 4.08 erg/cm(3) at T=250 K) of the ferromagnetic particles are determined. The volume fraction of the iron phase is estimated. (C) 2009 American Institute of Physics. [doi:10.1063/1.3234402]

    Gaussian approximation in the ising-model with long-range interaction / M. A. Popov // Theor. Math. Phys. - 1990. - Vol. 83, Is. 3. - P. 658-663, DOI 10.1007/BF01018036. - Cited References: 7 . - ISSN 0040-5779

Аннотация: The infinite hierarchy of equations for the cumulants of the correlation functions of the longitudinal spin components in the Ising model with long-range interaction corresponding to a Gaussian form of the spectral density is investigated. The invariance of the cumulants with respect to permutation of the vertices is used to decouple the hierarchy. A phase transition of the second kind is described by the obtained system of equations for the cumulants of the first three orders in a three-dimensional model.

Аннотация: Complexes of zigzag-type carbon nanotubes (CNTs) with transition metal atoms, scandium and titanium, were studied. It was demonstrated that the energy of binding of both atoms with a carbon surface decreases whereas the rate of diffusion along the surface increases with increasing nanotube diameter. The rate constant of migration of scandium atoms over a CNT surface are several orders of magnitude higher than that for titanium atoms, because the CNT surface-Sc atom binding energy is substantially lower.

Аннотация: Single crystals of Pb2Fe2Ge2O9 have been grown. They were subjected to X-ray diffraction, magnetic, neutron diffraction, Mossbauer and spin resonance studies. It has been established that Pb2Fe2Ge2O9 is a weak ferromagnet with a N,el temperature T (N) = 46 K, and the exchange and spin-flop transition fields have been estimated. It has been demonstrated that the weak ferromagnetic moment is actually the result of the single-ion anisotropy axes for the magnetic moments of different magnetic sublattices being not collinear.
