Abstract

Electrical resistivity measurements under high pressures up to 29 GPa were performed for oxypnictide compound LaFeAsO. We found a pressure-induced superconductivity in LaFeAsO. The maximum value of T _c is 21 K at ∼12GPa. The pressure dependence of the T _c is similar to those of LaFeAsO _1-xF _x series reported previously.
