Magnetotransport effects in granular Cd3As2 + MnAs structures at high pressures

  • 69 Accesses

  • 3 Citations

Abstract

The transport properties of granular Cd3As2 + MnAs (44.7% MnAs) composite structures have been studied near room temperature at high hydrostatic pressures of up to 9 GPa. The results demonstrate that the composite undergoes a structural phase transition and has a pressure-induced negative magnetoresistance.
