Short-Range Ordering in the Modified Honeycomb Lattice Compound SrHo2O4



S Ghosh, H. D. Zhou, L. Balicas, Jason S. Gardner, Yiming Qiu, C. R. Wiebe


The low temperature behaviour of single crystalline SrHo2O4 has been characterized by DC mag- netic susceptibility, heat capacity, and neutron scattering experiments. Our results show that despite the lack of magnetic long-ranged ordering in the presence of strong antiferromagnetic correlations, SrHo2O4 does not order down to 1.8 K. Elastic neutron scattering experiments show prominent magnetic di ffuse scattering correlated with a broad feature in the DC susceptibility at T = 4K, indicative of magnetic short-ranged ordering of the Ho3+ spins. Inelastic neutron scattering show the presence of 5 crystal field levels up to 80 K in energy, in agreement with the integration of the magnetic specfi c heat component yielding Rln5 entropy release. The magnetic short-ranged ordering is t to a nearest-neighbour interaction model with good agreement.
