N2 - The magnetic properties of Cr impurities in β-Ga2O3 are investigated by band-gap corrected density-functional calculation. We show that Cr impurities carry a local spin magnetic moment, but in the absence of external doping exhibit no magnetic interaction. Under n-Type doping conditions, however, a strong and directional long-range ferromagnetic interaction emerges, which diminishes again as carrier electron concentration is increased beyond a threshold. These results indicate carrier-mediated ferromagnetism in Cr-doped β-Ga2O3
