Magnetic field annihilators: invisible magnetization at the magnetic equator [PDF]

open access: yesGeophysical Journal International, 2003
SUMMARY Some distributions of magnetization give rise to magnetic fields that vanish everywhere above the surface, rendering these distributions of magnetization completely invisible. They are the annihilators of the magnetic inverse problem. Known examples are the infinite sheet with constant magnetization and the spherical shell of constant ...

Production of nanocrystalline soft magnetic powders with high Bs by an improved rapid-cooling water-atomization process

open access: yesAIP Advances, 2019
A powder of Fe83.3Si4B8P4Cu0.7 composition with D50 of 4.2 μm was prepared by the modified water atomization system named “HPWA/YK”. The obtained powder had a mostly amorphous single phase.

Simultaneous loss of interlayer coherence and long-range magnetism in quasi-two-dimensional PdCrO2

open access: yesNature 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 ...
