Magnetic Behavior of Sintered NdFeB Magnets on a Long-Term Timescale
Advances in Materials Science and Engineering, 2014 Stable polarization of permanent magnets over the lifetime of the application is an important aspect in electrical machine design. Specification of the long-term stability of magnet material is difficult, since knowledge of the phenomenon is incomplete ...

MAGNETIZATION OF AMORPHOUS MAGNETS
Le Journal de Physique Colloques, 1979 The temperature dependence of the distribution of the magnetic moment in an amorphous magnet, where the exchange interactions and the magnitude of the magnetic moment at O K are random variables, has been investigated. In particular, we considered the two-limiting cases, the one with the fixed spin and the other with the fixed interaction.

New technique for producing a strong multi-pole magnet [PDF]
, 1986 A new technique for producing strong multipole magnet is developed. A cylindrical magnet oriented with its easy axis of magnetization perpendicular to the cylinder axis is magnetized by a multipole magnetizer. This procedure results in a multipole magnet

Simultaneous loss of interlayer coherence and long-range magnetism in quasi-two-dimensional PdCrO2
Nature Communications, 2017 Incoherent transport is an important feature of many anisotropic quantum materials but often its origin is not well understood. Here, the authors show that in a layered quantum magnet, incoherence is driven by the interaction of electrons with spin ...
