摘要

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

GeC samples

where

pling between these two regions gives rise to exchange anisotropy and a change in sign at 20 K resulting in

rarely observed

inverted hysteresis loops.

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 (Cr

1−

)

GeC samples

where

is varied between 0.01 and 0.1. The Mn-poor regions form a reentrant cluster glass state below ∼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.
