Temperature-dependent magnetic properties. a Magnetization (M) and b RAHE as a function of Hext for Pt/Co/SiO2/Pt heterostructures with Hext perpendicular to the film plane and measurement temperature of 50, 300, and 400 K. c, d Temperature dependence of Ms, RAHE, and Hc. The error bars in c are defined as s.d. The Hc in (c) is obtained from M–Hext curve and that in (d) is extracted from RAHE–Hext curve
