title = "Observation of enhancement of the Morin transition temperature in iridium-doped α-Fe2O3 thin film by 57Fe-grazing incidence synchrotron radiation M{\"o}ssbauer spectroscopy",
abstract = "The Morin transition of a (0001)-oriented iridium-doped α-Fe2O3 thin film deposited on an Al2O3(0001) substrate was studied by 57Fe-grazing incidence synchrotron radiation M{\"o}ssbauer spectroscopy (GISRMS). Temperature-dependent spectra proved that the iridium doping markedly enhanced the Morin temperature of the α-Fe2O3 thin film; the iron spin directions were perpendicular to the film plane at temperatures below 100°C, while they were in-plane at temperatures above 150°C. The antiferromagnetic ordering was maintained far above 400°C. The results demonstrated the availabilities of 57Fe-GISRMS, which enables a very quick evaluation of the magnetism in antiferromagnetic ultrathin films at high temperatures.",
