Abstract

We have investigated the magnetic properties of the highly anisotropic layered ferromagnetic semiconductor CrI3 under hydrostatic pressure with the magnetic field along the easy axis of magnetization. At ambient pressure, CrI3 undergoes a second-order paramagnetic-to-ferromagnetic phase transition at TC=60.4 K. TC is found to increase sublinearly from 60.4 to 64.9 K as pressure increases from 0 to 1.0 GPa. With the increase in pressure, the transition becomes sharper while magnetization at low field decreases monotonically due to a decrease in magnetocrystalline anisotropy. The weak low-field anomaly at around 48 K, resulting from two-step magnetic ordering, also shifts toward higher temperatures with increasing pressure. The observed increase in TC and the decrease in magnetization could originate from a change in coupling between the layers and the Cr-I-Cr bond angle with pressure.
