Effect of pressure on magnetic phases of (Fe{sub}(1-x)Ni{sub}x){sub}49Rh{sub}51

摘要

The effect of high pressure and magnetic field on the stability of magnetic phase transitions in (Fe{sub}(1-x)Ni{sub}x){sub}49Rh{sub}51 has been studied. It has been shown that the increase in the Ni content suppresses the stability of the low-temperature antiferromagnetic phase and leads to its disappearance. Pressure on the other hand restores the stability to the antiferromagnetic order. These findings are explained using first-principles band-structure calculations.
