A magnetic glass state over the first-order ferromagnetic-to-antiferromagnetic transition in FeRh film

A magnetic glass state over the first-order ferromagnetic-to-antiferromagnetic transition in FeRh film

The intermetallic FeRh system has displayed tremendous fascination to investigators due to its remarkable physical properties and potential applications. Here we synthesized near-equiatomic FeRh films on MgO (001) substrate by magnetron co-sputtering of Fe and Rh, and our results revealed a magnetic...
