内容摘要:

   Antiferromagnetic (AFM) spintronics is an emerging field of research, which uses the antiferromagnets as the active spin-dependent elements for the next generation of spintronic applications. This talk will address three approaches predicted by density-functional theory calculations, involving new material platforms, which are promising for AFM spintronics. We demonstrate that room temperature AFM metal MnPd2 allows the electrical control of the Dirac nodal line by the Néel spin-orbit torque, leading to the sizable change of the spin-Hall conductivity. These approaches support the efficient manipulation and detection of the AFM order, which broaden the scope of material platforms that can be exploited in AFM spintronics.
