\"\"Robust spin injection and detection in antiferromagnetic thin films is a prerequisite for the exploration of antiferromagnetic spin dynamics and the development of nanoscale antiferromagnet-based spintronic devices. Existing studies have shown spin injection and detection in antiferromagnet-nonmagnetic metal bilayers; however, spin injection in these systems has been found effective at cryogenic temperatures only. A recent experiment done by Prof. Igor Barsukov at UC-Riverside experimentally demonstrated sizable interfacial spin transport in a hybrid antiferromagnet-ferromagnet system, consisting of Cr2<\/sub>O3<\/sub> and permalloy, which remains robust up to the room temperature. In collaboration with Prof. Igor Barsukov, PI-Cheng well explained the experimental data using a spin diffusion model and find evidence for the important role of interfacial magnon pumping in the signal generation. The experimental results, along with the intuitive theoretical model, bridge spin-orbitronic phenomena of ferromagnetic metals with antiferromagnetic spintronics and demonstrate an advancement toward the realization of room temperature antiferromagnetic spintronics devices.<\/p>\n
