Crystallographic and magnetic structure of TbFe 10V 2 and ErFe 10V 2

Abstract

The compounds TbFe 10V 2 and ErFe 10V 2 crystallize in the tetragonal ThMn 12 structure. The vanadium atoms exhibit a strong preference for occupying the 8i site. At room temperature both compounds have an easy magnetization direction parallel to the c axis. At 4.2 K both compounds behave differently. In TbFe 10V 2 the easy magnetization direction deviates from the c axis by 50°. In ErFe 10V 2 the easy magnetization direction is perpendicular to the c axis.
