Eucd2as2 under high pressure
WebAug 4, 2024 · Experimentally, we establish that the ground state of EuCd As changes from in-plane antiferromagnetic (AFM) to ferromagnetic at a critical pressure of 2\,GPa, which is likely characterized by the moments dominantly lying within the plane (FM ). The AFM -FM transition at such a relatively low pressure is supported by our DFT calculations.
