Magic d-electron number of doped ions for occurrence of ferromagnetic metal phase in Pr0.65Ca0.35Mn0.96A0.04O3

The electrical resistivity rho, Seebeck coefficient S and magnetization M have been measured for polycrystalline Pr0.65Ca0.35Mn0.96A0.04O3-doped with a vast variety of elements A. The ferromagnetic metal (FM) phase has been caused by doping only by Cr, Co, Ni, Ru and Ir. A necessary condition for th...

Zusammenfassung:The electrical resistivity rho, Seebeck coefficient S and magnetization M have been measured for polycrystalline Pr0.65Ca0.35Mn0.96A0.04O3-doped with a vast variety of elements A. The ferromagnetic metal (FM) phase has been caused by doping only by Cr, Co, Ni, Ru and Ir. A necessary condition for the electronic configuration of the dopants has been clarified to materialize the FM phase in this system.
