锰铋薄膜可以以两种晶相存在。测量了在淬火高温相制备的薄膜的居里温度、磁光和磁性能，并与正常低温相制备的薄膜进行了比较。180°C的低居里温度使淬火薄膜在光存储应用中更具吸引力。在不同的工作温度下，对两种薄膜进行了激光居里点写入实验。这一结果可以用两相MnBi膜的物理性质来解释，锰铋薄膜可以以两种晶相存在。测量了在淬火高温相制备的薄膜的居里温度、磁光和磁性能，并与正常低温相制备的薄膜进行了比较。180°C的低居里温度使淬火薄膜在光存储应用中更具吸引力。在不同的工作温度下，对两种薄膜进行了激光居里点写入实验。这一结果可以用两相MnBi膜的物理性质来解释。
Manganese bismuth films can exist in two crystallographic phases. The Curie temperatures, magneto‐optical, and magnetic properties of films prepared at the quenched high‐temperature phase were measured and compared with those of the films at the normal low‐temperature phase. The low Curie temperature of 180°C makes the quenched films more attractive for optical memory applications. Laser Curie‐point writing experiments have been performed on both types of films at various operating temperatures. The results can be explained on the basis of the physical properties of the two phases of MnBi films.Manganese bismuth films can exist in two crystallographic phases.
