摘要: We report the first observation of steps in hysteresis loop a high‐spin molecular magnet. propose that steps, which occur every 0.46 T, are due to thermally assisted resonant tunneling between different quantum spin states. Magnetic relaxation increases dramatically when field is neighborhood step. A simple model accounts for observations and predicts value anisotropy barrier consistent with inferred from superparamagnetic blocking temperature.
