Evolution of stress and magnetism during the first-order phase transition of MnAs/GaAs(0 0 1)

Description

We have investigated epitaxial MnAs/GaAs(0 0 1) films in the phase transition region between 10 deg. C and 40 deg. C where hexagonal, ferromagnetic α-MnAs and paramagnetic, orthorhomic β-MnAs coexist. Quantitative stress measurements with a cantilever beam magnetometer reveal that during the phase transition the atomic distances change only in the vertical direction providing insight into the nature of the exchange coupling mechanism
