a Polar angle dependence of the switching field. The green dotted line represents the fitted line for 1/cos θ. b Measuring time (tm)-dependent behavior of the switching field. Error bars represent the standard deviation from 35 independent measurements. c Switching state diagram as a function of the external field in the x-direction. d Effective DL field evaluated from the switching state diagram. The red dotted line represents the effective DL field estimated from the harmonic measurement. The error bars in the figures represent the standard error.
