原始语种摘要: Magnetic phase transitions in bcc FeRh0.95Ir0.05 alloy were investigated under high pressures up to 6.2 GPa by means of X-ray diffractometry using synchrotron radiation. The phase transition from antiferromagnetic to paramagnetic at high pressures with increasing temperature was confirmed to be a first-order phase transition accompanied by a volume expansion of about 0.3%. The mechanism of the first-order magnetic transition was interpreted in terms of spin fluctuation and magneto-volume effect.
