Investigation Of Field-induced Ferromagnetism In Pd-ni-fe-p Metallic Glass By X-ray Magnetic Circular Dichroism

摘要

We have applied x-ray magnetic circular dichroism to investigate the field-induced ferromagnetism in Pd_(40)Ni_(22.5)Fe_(17.5)P_(20) alloy. The experiment revealed that both Ni and Fe were in a divalent state and that the magnetic properties of the material were determined by the localized 3d electrons of the transition metals. No clear evidence of Ruderman-Kittel-Kasuya-Yosida-type interaction among magnetic clusters was observed. It is believed that the detailed balance of fundamental spin-orbit and exchange interactions as a function of temperature and applied magnetic field determine the different magnetic properties of the alloy.
