Spin disorder competing with positional symmetry breaking governs the metal-insulator behavior in oxide paramagnets
Jia-Xin Xiong, Xiuwen Zhang, Alex Zunger
Numerous transition-metal oxides have low-temperature antiferromagnetic (AFM) states and high-temperature paramagnetic (PM) phases, where the AFM state is usually insulating while…

Upward band gap bowing and negative mixing enthalpy in multi-component cubic halide perovskite alloys
Xiuwen Zhang, Fernando P. Sabino, Jia-Xin Xiong +1
Physical properties intermediate between constituents of alloys can be achieved as downward convex positive bowing, upward concave negative bowing, or zero bowing. Such bowing effe…

Tuning the magnetic properties of the spin-split antiferromagnet MnTe through pressure
Edison P. Carlisle, George Yumnam, Stuart Calder +6
The hexagonal antiferromagnet MnTe has attracted enormous interest as a prototypical example of a spin-compensated magnet in which the combination of crystal and spin symmetries li…
