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 5x107erg/cc at 500K, attractive for high temperature device applications . Much work has been carried out to understand this magnetic anisotropy mechanism . A recent calculation 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 .
