Ferromagnetic resonance studies in Co/SiO2 multilayers

The uniaxial in-plane and out-of-plane anisotropies of [Co/SiO2] 10 multilayers have been studied by ferromagnetic resonance, magnetometry and transmission electron microscopy. The surface and volume anisotropy constants are in the range of values typical for multilayers with Co and transition metals of the iron group. The influence of the intermixed Co–SiO2 region is discussed. # 2007 Elsevier...

Ferromagnetic resonance

Ferromagnetic Resonance

Ferromagnetism is used to characterize magnetic behavior of a material, such as the strong attraction to a permanent magnet. The origin of this strong magnetism is the presence of a spontaneous magnetization which is produced by a parallel alignment of spins. Instead of a parallel alignment of all the spins, there can be an anti-parallel alignment of unequal spins. This results in a spontaneous...

Use of video-tapes in psychological medicine.

It was in 1947 that perhaps the first use was made of closed-circuit television when the proceedings of five surgical operations were transmitted to a group of physicians at a medical meeting at Johns Hopkins (Berger, 1970). In psychiatry, the first reports of the use of closed circuit television in the teaching of medical students and psychiatric nurses, as well as residents were probably by W...
