Abstract:
Single crystals of the frustrated S=1/2 ferro-antiferromagnetic proximate square lattice material SrZnVO(PO4)2 are studied in magnetometric, calorimetric, neutron diffraction, and inelastic neutron scattering experiments. The measured spin wave spectrum reveals a substantial degree of magnetic frustration and a large quantum renormalization of the exchange constants. The H−T magnetic phase diagram is established. It features a novel presaturation phase, which appears for only one particular field orientation. The results are discussed noting the similarities and differences with the previously studied and similarly structured Pb2VO(PO4)2 compound.
