Temperature dependence of spin Hall magnetoresistance across the Néel temperature of CoO

Spin Hall magnetoresistance has been used to probe magnetic moments in magnetic insulator/heavy metal thin films. Here we explore the magnetic field-dependent magnetoresistance and the temperature-dependent magnetoresistance in a Pt/CoO/Pt trilayer near the Néel temperature of CoO. The obtained magn...

Summary:Spin Hall magnetoresistance has been used to probe magnetic moments in magnetic insulator/heavy metal thin films. Here we explore the magnetic field-dependent magnetoresistance and the temperature-dependent magnetoresistance in a Pt/CoO/Pt trilayer near the Néel temperature of CoO. The obtained magnetoresistance in an antiferromagnetic phase can be interpreted as SMR whereas the results in a paramagnetic one suggest the additional mechanism other than the conventional SMR.
