Abstract

Hole-doping effects by Ba substitution for La in La4-xBa2+xCu2O10 (0 ≤ x ≤ 1) have been studied to explore the possibilities of its metal-insulator transition and superconductivity. We have not detected any symptoms for metal-insulator transition, but found certain evidence for the hole-doping effect. We observed the dilution effect of Cu2+ spin by non-magnetic Cu3+ on the ferromagnetic transition temperature and the reduction of effective magnetic moment.
