Probing Anisotropy and Correlative Behavior in a 2D Magnet

ORAL

Abstract

Two-dimensional (2D) magnetism is known to be unstable in the isotropic Heisenberg model but can be realized through the introduction of magnetic anisotropy. This anisotropy leads to rich, highly symmetry-dependent exchange interactions which can introduce strong quasiparticle correlations. In a 2D magnet, signatures of magnetic and electronic anisotropy as well as strong correlations between charge, spin, and lattice have been reported. However, the exact effects of these correlations on the electronic states remain unclear. Here, using angle-resolved photoemission spectroscopy (ARPES), we studied the electronic structure of this 2D magnet. We probed detailed band structure changes as a function of magnetic ordering and external parameters. The observance of such coupling can have potential impacts on the understanding of correlative behavior in 2D magnets and the development of spintronic devices.
