Evidence of a Low Energy Anisotropy in GdCoIn $$_5$$ 5

Abstract

We investigate the effects of an applied magnetic field on the magnetic properties of the antiferromagnet GdCoIn 5 . The prominent anisotropy observed in the susceptibility below T N is rapidly suppressed by a field of just a few Tesla. Further evidence of this low energy-scale is obtained from magnetoresistance and magnetostriction experiments. The lattice length, particularly, shows a sudden change below 2 T when the magnetic field is applied perpendicular to the crystallographic ĉ-axis.

“…The theoretical description of the MS data needs also to account for the pronounced anisotropy observed in the magnetic susceptibilities below T N as it was reported pre- viously [10,16]. Interestingly, the observed difference between theâ-axis andĉ-axis susceptibilities is rapidly suppressed as the magnetic field is raised above ∼ 1 T [16,17].…”

“…In CeScGe the transition temperature is high enough (T N ∼ 47 K) that the first excited crystal split doublet of the Ce 4f orbital cannot be ignored for a detailed description [9]. In the Gd compounds the crystal field is generally very small [10,11],…”
