Experimental and computational analysis reveals room-temperature zero-field-cooling exchange bias in strained Mn3.1Sn0.9, highlighting potential applications in antiferromagnetic spintronics.
. Magnetic analysis and first-principles calculations reveal that the ZFC EB arises from the strong exchange interaction between the non-coplanar antiferromagnetic Mn kagome sublattice occupying normal Mn sites and the collinear ferromagnetic Mn sublattice occupying Sn sites. This discovery is of great significance for the application of ZFC EB in antiferromagnetic spintronic devices.
