A puzzling insensitivity of magnon spin diffusion to the presence of 180$^circ$ domain walls in a ferrimagnetic insulator

Posted by klaurent Cornell

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Ruofan Li, Lauren J. Riddiford, Yahong Chai, Minyi Dai, Hai Zhong | Summary: We present room-temperature measurements of magnon spin diffusion in epitaxial ferrimagnetic insulator MgAl$_{0.5}$Fe$_{1.5}$O$_{4}$ (MAFO) thin films near zero applied magnetic field where the sample forms a multi-domain state. Due to a weak uniaxial […]
