α‐Fe2O3 and α‐Fe2O3/graphene oxide (GO) nanocomposites are synthesized by solvothermal method in acetonitrile medium at 200 °C. XRD studies reveals the formation of α‐Fe2O3 and α‐Fe2O3/GO nanocomposites. Raman studies indicate that GO in α‐Fe2O3/GO system was more disordered than GO. The enhanced low temperature magnetic saturation and coercivity in α‐Fe2O3 and α‐Fe2O3/GO are related to frozen canted spins. Blocking temperature of α‐Fe2O3/GO is 348 K, which also shows higher coercivity of the order of about 3064 Oe at 5 K. The α‐Fe2O3/GO composite exhibits thermal hysteresis at Morin transition (ΔTM = 11 K).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
