Abstract

X-ray magnetic circular dichroism (XMCD) measurements have been performed under high pressure and used to study the disordered Fe₇₂Pt ₂₈ Invar alloy in conjunction with x-ray diffraction. The high spin to low spin state transition is observed by both techniques and is compared with previous work. Furthermore, XMCD gives the first evidence of the complete disappearance of the magnetic moment at high pressure in this alloy. It also proves the existence of an hysteresis cycle due to the pressure-dependent magnetic moment.
