Manganese arsenide (MnAs) is an intermetallic compound, an arsenide of manganese. It forms ferromagnetic crystals with hexagonal (NiAs-type) crystal structure, which convert to the paramagnetic orthorhombic β-phase upon heating to 45 °C (113 °F). MnAs has potential applications in spintronics, for electrical spin injection into GaAs and Si based devices.[2]
