Influence of palladium on the unidirectional anisotropy field in NiMn disordered systems

Thermomagnetic hysteresis effects in NiMn and NiMnPd thin films

“…We note that the measured loops for both cases display either a smooth and gradual, or a sharp and boxlike shape. 1 Similar behavior has been reported on NiMn films ͑whether amorphous or not͒ by Hauser and Bernardini. It is also interesting to note that the ZFC and FC loops are similar in most respects, but with the difference that the FC magnetization changes much more abruptly near the coercive field compared to the corresponding ZFC case.…”

Nanograin ferromagnets from non-magnetic bulk materials: the case of gold nanoclusters

“…Besides to help the doping process, the role of the ligand on the surface turns out to influence only the strength of the spin-orbit coupling. A similar description probably works also in the case of Pd nanograins where the importance of similar effects have been pointed out [46][47][48][49][50] . We further note that if an arbitrary non-magnetic and metallic compound becomes ferromagnetic at nanoscales, and presents similar material properties as detailed for Au at the beginning of Section II, the here presented theory would explain this behavior.…”
