Magnetic characterization of Cr2O3 thin films on V2O3 electrodes. (a) Optical second harmonic generation intensity from 30 nm thick Cr2O3 on V2O3 electrode at room temperature (orange: analyzer along the x-direction ([\(11\overline{2}0\)]), blue: analyzer along y-direction ([\(\overline{1}100\)])) and theoretical plot of electric dipole signal (Eq. (1b)) when analyzer is fixed along x-direction (dash-orange) and y-direction (dash-blue) showing the agreement between experimental result and theory. (b) Exchange bias field (top panel) and coercive field (bottom panel) as a function of temperature from Pt (5 nm)/Permalloy (Py) (4 nm)/Cr2O3 (30 nm)/V2O3/Al2O3 and Pt (5 nm)/Py (4 nm)/Al2O3 (labeled Py control) heterostructures. The Py control data shows both \(\pm \) 5,000 Oe field cool scans.
