Аннотация: The magnetic properties of three-layer Co-Ge magnetic films have been studied experimentally as a function of technological conditions of their deposition. It has been found that the films deposited at a high deposition rate have a granular structure, and the films obtained at a low deposition rate have an X-ray amorphous structure. Electron microscopy and nuclear magnetic resonance studies have demonstrated that, at the same cobalt layer thickness, the semiconductor granule sizes depend on the average semiconductor layer thickness and correlate with the formation of different cobalt phases (amorphous, cubic, and hexagonal). The thermomagnetic properties of the films have been investigated. © 2014 Pleiades Publishing, Ltd.

Аннотация: In Letter the results of experimental and theoretical investigations of magnetic properties in trilayer Co/Ge/Co films are represented. The temperature dependences of films, being two phases in respect of magnetism, are studied. Experimental results are explained in the frameworks of impurity model, when the hexagonal cobalt grains are considered as quasi-Ising particles distributed chaotically and dissolved within an isotropic matrix of cubic cobalt. The fields of magnetization rise on the T-H plane are determined. (c) 2006 Elsevier B.V. All rights reserved.

Аннотация: The results of experimental study of magnetic properties in permalloy/bismuth/permalloy trilayer films synthesized for the first time are presented. Measurements of magnetic field and temperature dependences of magnetization have shown that the interlayer coupling depends on bismuth spacer thickness. The dependence of saturation magnetization of the system on semimetal thickness has been found. Possible mechanisms responsible for the observed features of behavior are discussed.

Аннотация: We report our experimental observation of interlayer exchange coupling phenomena in CoO/Cu/Co trilayers with systematic variation of Cu spacer layer thickness as well as temperature. It has been found that there exists a clear indication of nonmonotonically varying oscillatory interlayer exchange coupling. The amplitude of oscillation increases, reaches to the maximum, and decreases with increasing Cu spacer thickness from 1 to 16 atomic layers for all temperature ranges between 70 and 200 K.

Аннотация: The results of NMR studies of film structures in a cobalt-germanium system as a function of the cobalt layer thickness are presented. Two phases of cobalt, one is a face-centered cubic phase and the other is presumably a Co-Ge alloy with a weakly ferromagnetic order, have been found to exist. A "dead" layer no more than 2 nm in thickness is formed at the interface.

Аннотация: Three-layer Co/Ge/Co films have been studied using electron magnetic resonance. It has been established that the resonance spectrum of the film is a superposition of two Lorentzian lines. It has been found that the anisotropy induced at the cobaltaEuro'germanium interface makes the main contribution to the resonance spectrum and determines its features. The temperature dependences of the anisotropy field and the parameters of the interlayer exchange have been measured. The interlayer interactions exhibit an antiferromagnetic character and have been explained in terms of a model similar to the description of superexchange in magnetic dielectrics.
