Abstract :
The relation between deposition conditions of Bi and Mn layers and crystal growth of MnBi were investigated to reduce the MnBi annealing temperature for its application to a magneto-optical disk. We found that higher c-axis orientation of the hexagonal Bi layer and lower Mn oxide concentration in the Mn layer reduces the annealing temperature. Growth of MnBi below 150°C, which is much lower than the decomposition temperature of photo-polymer (about 200°C), was achieved by optimizing deposition conditions of Bi and Mn layers
