Understanding Antiferromagnetic Coupling in Lead-Free Halide Double Perovskite Semiconductors.

ABSTRACT: Solution-processable semiconductors with antiferromagnetic (AFM) order are attractive for future spintronics and information storage technology. Halide perovskites containing magnetic ions have emerged as multifunctional materials, demonstrating a cross-link between structural, optical, electrical, and magnetic properties. However, stable optoelectronic halide perovskites that are antiferromagnetic remain sparse, and the critical design rules to optimize magnetic coupling still must be developed. Here, we combine the complementary magnetometry and electron-spin-resonance experiments, together with first-principles calculations to study the antiferromagnetic coupling in stable Cs₂(Ag:Na)FeCl₆ bulk semiconductor alloys grown by the hydrothermal method. We show the impor
