中文摘要	We report discovery of ferromagnetism in (LaCa)(ZnMn)SbO isostructural to the well-studied iron-based superconductor LaFeAs(O1-x F (x) ). Spin is induced by partial substitution of Mn2+ for Zn2+, 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 (La0.95Ca0.05)(Zn1-x Mn (x) )SbO. The Hall coefficient measurement indicates p-type carrier for (La0.95Ca0.05)(Zn0.9Mn0.1)SbO with concentration of n similar to 10(20) cm(-3) showing anomalous Hall effect below T (C).
