研究了采用连续真空沉积和退火工艺制备的PtMnSb薄膜的磁光性能。经5 0 0 °C处理的PtMnSb薄膜在6 33 nm处表现出7.3×10 5°的法拉第旋转角(θF)和1.8°的极克尔旋转角(−K)。它们在4 0 0~90 0 nm波长范围内具有良好的透光性，在6 33 nm处的吸收系数(α)为3.2×10 5 cm−1。在633 nm处的磁光优值系数为：透射光为2θF/α=4.6deg，反射光为(R)1/2θK=0.99deg。
Magneto‐optical properties for PtMnSb thin films, prepared by sequential vacuum deposition and annealing, are examined. PtMnSb thin films annealed at 500 °C exhibit a large Faraday rotation (θF) of 7.3×105 deg cm−1 as well as a large polar Kerr rotation (θK) of −1.8° at 633 nm. They transmit light well in the 400–900 nm wavelength range with an absorption coefficient (α) of 3.2×105 cm−1 at 633 nm. The magneto‐optical figures of merit at 633 nm were 2θF/α =4.6 deg for transmitted light and (R)1/2θK =0.99 deg for reflected light.
