Ferromagnetic resonance in amorphous ferromagnet

Solid State Communications, 1984
Abstract The peculiarities of the ferromagnetic resonance of an amorphous ferromagnet in which a certain number of atoms forms the two-level systems are studied. The logarithmic dependence upon the temperature and the applied magnetic field of the frequency shift of the ferromagnetic resonance is obtained.

Superconductivity and Ferromagnetism

IBM Journal of Research and Development, 1962
Superconductivity and ferromagnetism were considered exclusive phenomena for many decades. Ever since Kamerlingh Onnes' discovery that strong magnetic fields will destroy superconductivity it had been assumed that the large internal, or Weiss field, in a ferromagnet would never permit the occurrence of superconductivity.

Criteria for ferromagnetic–insulator–ferromagnetic tunneling

Journal of Magnetism and Magnetic Materials, 2002
The Rowell criteria, commonly used to identify tunneling in magnetic tunnel junctions (MTJ), are scrutinized. While neither the exponential-thickness dependence of the conductivity nor fits of non-linear transport data are found to be reliable tunneling criteria, the temperature-dependent conductivity does remain a solid criterion.

Tunneling conductance and magnetoresistance of ferromagnet/ferromagnetic insulator (semiconductor)/ferromagnet junctions

Physical Review B, 1998
The tunneling conductance (TC) and magnetoresistance (TMR) are investigated for magnetic junctions consisting of two ferromagnetic electrodes separated by a ferromagnetic insulator (semiconductor). The investigations are based on the nearly-free-electron approximation.

Ferromagnetism

1997
Abstract The termferromagnetismis used to characterize strongly magnetic behavior, such as the strong attraction of a material to a permanent magnet. The origin of this strong magnetism is the presence of a spontaneous magnetization produced by a parallel alignment of spins.
