Magnetic field dependence of the magnetic torque and diamagnetic susceptibility. a Torque curves at various temperatures. Each torque curve exhibits hysteresis between the up and down sweeps of the magnetic field, due to pinning of the flux lines. The irreversibility field (Hirr) is defined in the inset. b Torque curves at various field angles. The de Hass-van Alphen oscillations are observed at high fields (inset). c Magnetic field dependence of the diamagnetic susceptibility −dMz/dHz at various temperatures. The −dMz/dHz value is obtained from the angular dependence of the torque curve (see SI A). Arrows indicate the kink fields Hkink
