Abstract

The low temperature phase (LTP) MnBi is known to exhibit the unique temperature dependence of a magnetic anisotropy constant K which increases with temperature from about 100K to 500K, reaching to about 5×10⁷erg/cc at 500K^1-4, attractive for high temperature device applications. Much work has been carried out to understand this magnetic anisotropy mechanism. A recent calculation⁴ showed a strong correlation of the lattice constant with the magnetic anisotropy energy of the LTP MnBi, but the experimental results are at variance with the calculation. The present study aims to elucidate the mechanism for its temperature dependence of LTP MnBi thin films.
