Magnetic Phase Diagram of Geometrically Frustrated SrHo2O4

DOI

In SrHo2O4, the Ho3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric frustration. In zero field, magnetic order is established at 0.68 K, and the magnetic ground state is made up of two distinct components: a long-range ordered k = 0 phase and a quasi-1D structure. We propose to use the WISH diffractometer to study the low T magnetic phases in a single crystal sample of SrHo2O4 as a function of the applied field. From bulk property measurements, an up-up-down collinear spin state is stabilised around 0.8 T when H//b. However, when H//c, completely different behaviour is expected, with the applied field destabilising the long-range order and giving rise to some shorter range correlations. These observations resemble the behaviour seen around a quantum critical phase transition.
