Vibrating-coil magnetometry of the magnetic phase diagram of Gd₂Ga₅O₁₂ — •Markus Kleinhans and Christian Pfleiderer — Physik-Department, Technische Universität München, D-85748 Garching, Germany

Magnetic frustration attracts great interest since it leads to exotic magnetic orders like spin liquids, spin glasses and spin ice all associated with the geometric frustration of magnetic spins. We report vibrating coil magnetometry down to mK temperatures [2] of the frustrated system Gd₂Ga₅O₁₂[1,3,4]. Based on the magnetization measured in a spherical sample for field along ⟨100⟩, ⟨110⟩, and ⟨111⟩ we track the magnetic phase diagram as a function of field orientation in great detail.
