Abstract
Magnetic states of Fe, Co, and Ni hydrides under pressure have been investigated by X-ray magnetic circular dichroism (XMCD) at the K-edge. At room temperature, Fe, Co, and Ni metals are hydrogenated to ferromagnetic FeH, ferromagnetic CoH, and paramagnetic NiH, respectively. A sharp XMCD profile is observed after hydrogenation, which is attributed to the hydrogen-induced reconstruction of the electronic structure. The pressure dependence of XMCD demonstrates that the ferromagnetic state of FeH is less stable than that of CoH under pressure.
