[17p-F202-8] Effects of hydride ion substitution to LaMnPO1-xHx
Keywords:Oxypnictide, Metal-Insulator transition, Hydride ion
We investigated the magnetic properties of LaMnPO1-xHx isostructural to 1111-type iron-based superconductor LaFeAsO. With increase of x, LaMnPO1-xHx was converted from antiferromagnetic insulator to ferromagnetic metal with a ferromagnetic transition temperature Tc of at 75 K for nominal x = 0.5. The Tc of LaMnPO1-xHx is smaller than that of LaMnAsO1-xHx with same x, indicating the difference of antiferromagnetic interaction through pnictgen p orbital.
