Exploring Magnetism of Lead-free Halide Double Perovskites: A High-Throughput First-Principles Study
We have performed a comprehensive, first-principles high-throughput study of the magnetic properties of halide double perovskites, $Cs_2BB^\prime Cl_6$, with magnetic ions occupying one or both B and B$^\prime$ sites. Our findings indicate a general
