Magnetic structure of a Pr-based antiferromagnet with competing interactions

Abstract: Rare-earth based correlated materials often host competing interactions and electronic ground states associated with different degrees of freedom. We have examined a Pr-based antiferromagnet which has competing antiferromagnetic and ferromagnetic interactions. We find that applying hydrostatic pressure induces a new low-temperature first-order transition, and it is of particular interest to determine its nature, and whether it corresponds to nematic ordering. In order to understand the electronic ground state and magnetism of the system, we propose to perform neutron diffraction on both powder and single crystal samples using the WISH diffractometer, so as to determine the detailed magnetic structure and the temperature dependence of the order parameter. Knowing whether the magnetic order breaks the lattice rotational symmetry will be important for uncovering possible nematicity.
