Extended Data Fig. 6

a, X-ray diffraction spectrum. Inset: Schematic of the RuO2/MgO heterostructure. b, Normalized in-plane magnetization of the Pt/CoFe/RuO2/MgO stack as a function of magnetic field at 50 K. c, Comparison of the in-plane coercivity field of Co90Fe10 (CoFe) films in a Pt/CoFe/RuO2/MgO heterostructure and a Pt/CoFe/MgO heterostructure. Inset: Schematic of a RuO2/MgO heterostructure capped by a 5-nm-thick CoFe layer and a 2-nm-thick Pt top layer. d, In-plane exchange bias field of the Pt/CoFe/RuO2/MgO heterostructure versus temperature.
