Nature of the magnetic and structural phase transition in MnAs/GaAs(001)
In the bulk the structural and magnetic phase transitions between α- and β-MnAs are coupled and proceed abruptly by first order. In heteroepitaxially constrained MnAs/GaAs(001) films, on the other hand, the two phases coexist at 10-40 °C and the magnetization decreases continuously with temperature....
