Fig. 5. Theoretical analysis of the magnetic anisotropy.
(A) The magnetic anisotropy energy ∆ plotted as a function of Cl SOC (αCl) by fixing the SOC of Cr to unity (αCr = 1). (B) ∆ plotted as a function of the Cr SOC by switching off the Cl SOC (αCl = 0). (C) The anisotropy energy as a function of the SOC in Cr and Cl, showing a competition between in-plane and out-of-plane anisotropies tuned by αCr and αCl.
