Аннотация: The results of an investigation on the generation of higher harmonics under the passing of a low frequency current in HTSC ceramics by microwave spectroscopy methods are presented. It is found that the generation of only even harmonics occurs. The dependence of the signal upon the harmonic number and. as an example for the second harmonic, the temperature dependences of the microwave response parameters are discussed.

Аннотация: The resonance absorption in Bi2CuO4 single crystals was found in the frequency range 35-80 GHz for H(perpendicular-to)C4 Case and it was absent for H(parallel-to)C4 case. The frequency-field dependence for H(perpendicular-to)C4 case at 4.2 K is typical for easy-plane antiferromagnets with weak magnetic anisotropy in this plane. In contrast to the sublattice magnetization of Bi2CuO4 the resonance parameters depend strongly on the temperature below 20 K. Besides, the resonance field has a considerable jump at TN which ls not typical for second order phase transitions.

Заглавие : A study of the microwave dielectric permittivity of liquid crystals in electric and magnetic fields
Место публикации : Tech. Phys. - 1998. - Vol. 43, Is. 1. - P.105-109. - ISSN 1063-7842, DOI 10.1134/1.1258946
Примечания : Cited References: 8
Аннотация: A microwave detector based on a self-sustained oscillator circuit is proposed as a means to investigate the real and imaginary components of the dielectric permittivity of liquid crystals in external electric and magnetic fields. Results are given for measurements of a 500 MHz oscillator frequency for two types of nematic crystals, 5CBP and MBBA. Fundamental regularities are identified in the behavior of the microwave dielectric permittivity of samples in electric and magnetic fields. It is shown that the minimum of the high-frequency dielectric loss in liquid crystals correspond to a situation in which the long axes of the molecules are oriented parallel to the direction of the microwave electric field.

Аннотация: We investigate theoretically the dynamics of squeezed state generation in nonlinear systems possessing a transition from regular to chaotic dynamics in the limit of a large number of photons. As an example, the model of a kicked Kerr oscillator is considered. We show that at the transition to quantum chaos the maximum possible degree of squeezing increases exponentially in time, in contrast to the regular dynamics, where the degree of squeezing increases only powerwise in time. We demonstrate the one-to-one correspondence of the degree of squeezing and the value of the local Lyapunov instability rate in the corresponding classical chaotic system.

Аннотация: We study the dynamics of an electron in a standing wave of a microwave field. For large field amplitude the system undergoes a transition to a chaotic regime which is shown to be entirely related with the transition to relativistic dynamics. A possible laboratory experiment is shortly discussed.

Заглавие : Influence of the transport current on the magnetoelectric properties of La0.7Pb0.3MnO3 single crystals with giant magnetoresistance in the microwave region
Место публикации : Phys. Solid State: AMER INST PHYSICS, 1999. - Vol. 41, Is. 11. - P1842-1849. - ISSN 1063-7834, DOI 10.1134/1.1131111

Аннотация: The results of experiment on the influence of a direct current and a low-frequency alternating current, as well as a magnetic field, on the microwave-range conductivity sigma(MW) of Ln(0.7)Pb(0.3)MnO(3) single crystals with giant magnetoresistance are presented. The greatest sensitivity of the samples toward the effects of a current is observed in the temperature range corresponding to the dc magnetoresistance maximum. The response signal of a sample in the microwave range to the effects of an alternating current of a low frequency f(0) has a nonlinear character. As f(0) is varied in a magnetic field, the amplitude of the response signal varies with the appearance of resonance peaks. The results obtained are interpreted within an approach based on the coexistence of two phases having different conductivities in the doped manganite crystals. This two-phase interpretation is supported by data from magnetic-resonance investigations, which demonstrate the existence of two magnetic phases over a broad temperature range in Ln(0.7)Pb(0.3)MnO(3) single crystals.

Заглавие : Resonant microwave conductivity response to ac current in La0.7Pb0.3MnO3 crystals
Место публикации : Phys. Solid State: AMER INST PHYSICS, 1999. - Vol. 41, Is. 12. - P2008-2013. - ISSN 1063-7834, DOI 10.1134/1.1131144

Аннотация: An experimental study of the effect of low-frequency transport current on the microwave conductivity of single-crystal La0.7Pb0.3MnO3 is reported. In the absence of an external magnetic field, the microwave conductivity response to a current follows a relaxation behavior. In a nonzero external magnetic field, the response spectrum exhibits a peak of resonant amplitude enhancement. The resonant response has a nonlinear nature. The temperature and field dependences of the main parameters of the microwave response correlate directly with the behavior of the magnetoresistance. The results obtained are analyzed within the oscillator approximation. Electronic phase separation is proposed as a possible mechanism for the current action. (C) 1999 American Institute of Physics.

Аннотация: The transmission of a TE microwave field with a frequency omega through Gamma, T, and X waveguide junctions filled with a ferromagnetic is considered. These junctions are known to have bound states with below-cutoff frequencies. A probing microwave radiation with a frequency Omega applied to the scattering region generates magnetic oscillations with frequencies omega + n Omega (where n = 0, +/-1, +/-2, ...), which resonantly combine with the bound waveguide states. This effect provides for a new method of studying bound waveguide states and efficiently controlling the transmission of microwave radiation. (C) 2001 MAIK "Nauka/Interperiodica".
