Abstract

We report discovery of ferromagnetism in (LaCa)(ZnMn)SbO isostructural to the well-studied iron-based superconductor LaFeAs(O_1-x F _x ). Spin is induced by partial substitution of Mn²⁺ for Zn ²⁺, while charge is induced by substitution of Ca²⁺ for La³⁺ within the parent compound LaZnSbO. Ferromagnetism with Curie temperature (T _C) is observed up to 40 K at the spin doping 0.15 by introducing Mn²⁺ into the Zn²⁺ sites for (La _0.95Ca_0.05)(Zn_1-x Mn _x )SbO. The Hall coefficient measurement indicates p-type carrier for (La _0.95Ca_0.05)(Zn_0.9Mn_0.1)SbO with concentration of n∼10²⁰ cm^-3 showing anomalous Hall effect below T _C.
