From: Room-temperature intrinsic ferromagnetism in epitaxial CrTe2 ultrathin films
a Temperature dependent magnetization curves of the films with various thicknesses under field-cooled mode. The magnetic field is applied along the out-of-plane direction with a magnitude of 1000 Oe. The high TC is preserved with thickness decreasing to 3 ML. b, c Magnetic hysteresis loops of 7 ML CrTe2 at different temperatures with external fields along the perpendicular (b) and parallel orientation (c) with respect to sample plane, indicating a strong out-of-plane magnetic anisotropy. d Enlarged hysteresis loops of 7 ML CrTe2 at 300 K, where the intrinsic ferromagnetism and PMA still maintains. Top inset: temperature dependence of Ku for 7 ML CrTe2, where the Ku is preserved at 300 K, despite the lower intensity with the increase of temperature.
