Electrical resistivity of FeAs, FeAs₂ and Fe₂As at homogeneous high pressures

Electrical resistivity of binary compounds containing iron and arsenic, FeAs, FeAs₂ and Fe₂As, is measured at homogeneous high pressures up to 15 GPa. The obtained results indicate the absence of pressure-induced superconductivity for these compounds in the specified pressure range. A new ground state possibly emerges in FeAs above 3 GPa. (paper)
