Effect of strain on the local phase transition temperature of MnAs/GaAs(001)

The effect of strain on the local phase transition temperature of MnAs/ GaAs was discussed. It was found that the characteristics temperature T* at which the as-grown films transformed to the paramagnetic β-phase was locally shifted up towards the value of unstrained bulk MnAs. The analysis showed t...

Crynodeb:The effect of strain on the local phase transition temperature of MnAs/ GaAs was discussed. It was found that the characteristics temperature T* at which the as-grown films transformed to the paramagnetic β-phase was locally shifted up towards the value of unstrained bulk MnAs. The analysis showed that the film areas exhibiting the higher T* were identified as the region in which the strain in the MnAs film was allowed to relax.
