Coexistence of Ferromagnetic and a Re-entrant Cluster Glass State in the Layered Quaternary (Cr1-x,Mn-x)(2)GeC
Materials research letters, v 2(4)
01 Jan 2014
Abstract
Herein we present evidence for the coexistence of a Mn-rich ferromagnetic (FM) state and a Mn-poor reentrant cluster glass state in bulk, polycrystalline, layered (Cr1-x,Mn-x)(2)GeC samples, where x is varied between 0.01 and 0.1. The Mn-poor regions form a reentrant cluster glass state below similar to 30 K. The Mn-rich regions become FM at Curie temperatures that increase with increasing Mn content. The interface coupling between these two regions gives rise to exchange anisotropy and a change in sign at 20 K resulting in, rarely observed, inverted hysteresis loops.
