a Magnetization hysteresis of sample-Ox shows that GdxCo100−x is close to magnetic compensation at room temperature, characterized by the small saturation magnetization. b Anomalous Hall effect hysteresis loop as a function of oxidation duration and ambient exposure duration. c Slope of the high field region as a function of external field angle from the \(\hat{z}\)-axis. With this technique, the canting angles θB are found to be 22.5° for sample-Ox after 230 s of oxygen plasma treatment and 1-day ambient exposure where the slope is the minimum. d 13.5° canting is found for sample-Ox after 230 s of oxygen plasma treatment and 58 days ambient exposure where the slope is the minimum.
