Anisotropic Magnetism in Gd${}_2$B${}_5$

Abstract

We report the synthesis of single crystals of Gd${}_2$B${}_5$ through a ruthenium-gadolinium flux method. The Gd${}_2$B${}_5$ system is a member of the monoclinic $P21/c$ (No. 14) space group and realizes lattices of gadolinium atoms in the $(100)$ plane. We characterized the sample through orientation-dependent electrical transport, magnetization, magnetic torque, and heat capacity measurements to probe the magnetic anisotropy of the system and map out its phase diagram. Gd${}_2$B${}_5$ realizes two zero-field ordered phases M${}_1$ and M${}_2$, as well as a third field-induced ordered phase M${}_{\perp }$ arising when the magnetic field is applied in the $(100)$ plane.
