Spin-reorientation phenomena in (Tb<i>x</i>Er1−<i>x</i>)TiFe11 systems

Abstract

Spin-reorientation phenomena in (TbxEr1−x)TiFe11 systems have been studied over the temperature range from 20 to 1000 K using susceptibility measurement. In this alloy series, the lattice constants, both a and c, increase with increasing x, as expected from the lanthanide contraction. For x&amp;lt;0.5, the (TbxEr1−x)TiFe11 systems were found to exhibit axial-to-conical spin-reorientation transitions with a Tsr decrease with increasing x. However, for x≳0.5, the spin-reorientation transitions have been found to be axial-to-planar, on cooling, and the Tsr increases with increasing x. The magnetic phase diagram of (TbxEr1−x)TiFe11 has been constructed.
