Magnetic dynamics in the high-pressure phase of antiferromagnet MnPS3
The MPX3 materials (M = Fe, Ni, Mn; X = S, Se) are a family of quasi-2D antiferromagnetic insulators, with most sharing a similar monoclinic unit cell and C2/m space group. The metal M2+ ions form a honeycomb lattice in the ab planes, which are weakly coupled by van der Waals forces. These layered magnets are of significant current interest in low-dimensional materials communities. Our previous studies show that MPX3 materials undergo two structural transitions under pressure, the second of which coincides with metallisation or the emergence of superconductivity. These transitions are also seen to dramatically modify the magnetic structure in these compounds. MnPS3 undergoes the first transition at the lowest pressure in the family and has dynamics well studied previously at ambient pressure. We propose to advance the existing work by measuring the evolution of magnetic dynamics into the first high pressure phase of MnPS3 for the first time. We will use high-pressure apparatus at low-temperature on IN5 to measure inelastic magnetic scattering above the 2 GPa transition. This work will also help to develop high pressure capabilities for inelastic measurement at the ILL.
