    • All preparative procedures were performed in a glove box filled with purified Ar gas. Until the sample was mounted on the cantilever, it had been kept in argon atmosphere or in a vacuum desiccator

    • A torque signal of 1 in the units of the vertical axis in Figs. 2 and 4 corresponds to a 4% change in the piezoresistance. Since the linear response region of the cantilever is limited, typically below a few percentage of the resistance change, the shapes of hysteresis loops with large torque, e.g., one at θ = 60° 0.3 K in Fig. 4 a, may be distorted
