## Abstract The first order phase transition between ferromagnetic Ξ±βMnAs and paramagnetic Ξ²βMnAs in nanoscale disks etched out of an epitaxial MnAs film on GaAs(001) is studied by means of Xβray diffraction and magnetic force microscopy. The temperature hysteresis loop is observed to be expanded w
