Magnetic-field dependence of spin-phonon relaxation and dephasing due to g-factor fluctuations from first principles
Joshua Quinton, Mayada Fadel, Junqing Xu +4
The electron spin decay lifetime in materials can be characterized by relaxation (T1) and irreversible (T2) and reversible (T2*) decoherence processes. Their interplay leads to a c…

Anomalous Hall effect from inter-superlattice scattering in a noncollinear antiferromagnet
Lilia S. Xie, Shannon S. Fender, Cameron Mollazadeh +11
Superlattice formation dictates the physical properties of many materials, including the nature of the ground state in magnetic materials. Chemical composition is commonly consider…

Spin Dynamics in Hybrid Halide Perovskites -- Effect of Dynamical and Permanent Symmetry Breaking
Kejun Li, Junqing Xu, Uyen N. Huynh +7
The hybrid organic-inorganic halide perovskite (HOIP), for example MAPbBr3, exhibits extended spin lifetime and apparent spin lifetime anisotropy in experiments. The underlying mec…
