Of magnetic van der Waals materials, TMPS3 with TM=transition metal elements have attracted significant attentions as it can exhibit the three fundamental magnetic model of Ising (FePS3), XY (NiPS3) and Heisenberg (MnPS3) Hamiltonian depending on the TM elements. Using these materials, we have studied some of the fundamental theorems of modern magnetism. In addition, we have also investigated how correlation physics plays a role in the optical spectroscopy data. In this talk, I will demonstrate how we can use this unique magnetic property of these materials to learn of the old physics.
