Effect of pressure and interstitial atoms on magnetic properties of LuFe₁₁Ti Intermetallics

Abstract

Magnetisation and magnetocrystalline anisotropy of the LuFe 11 Ti intermetallics have been studied under pressure up to 1.2 GPa in temperatures from 5 K to 350 K using a miniature CuBe pressure cell and a SQUID magnetometer. A decrease of Fe-moment under pressure is compatible with the increase of Fe-moment in hydride and nitride of LuFe 11 Ti. A complex dependence of magnetocrystalline anisotropy on volume of the elementary crystal cell of LuFe 11 Ti and its hydride and nitride has been observed.
