Abstract

The epitaxially grown MnAs films on GaAs(001) were studied using variable-temperature magnetic force microscopy (VT-MFM). The MnAs film underwent a first order structural phase transition around a critical temperature of 40°C. It was found that, due to the strain involved, the ferromagnetic α-MnAs and paramagnetic β-MnAs phase coexisted as stripes along MnAs[0001].
