We report discovery of ferromagnetism in(LaCa)(ZnMn)SbO isostructural to the well-studied iron-based superconductor LaFeAs(O1 xFx).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(TC)is observed up to 40 K at the spin doping 0.15 by introducing Mn2+into the Zn2+sites for(La0.95Ca0.05)(Zn1 xMnx)SbO.The Hall coefficient measurement indicates p-type carrier for(La0.95Ca0.05)(Zn0.9Mn0.1)SbO with concentration of n~1020cm 3showing anomalous Hall effect below TC.
We report discovery of ferromagnetism in (LaCa) (ZnMn) SbO isostructural to the well-studied iron-based superconductor LaFeAs (O1 xFx). 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 (TC) is observed up to 40 K at the spin doping 0.15 by introducing Mn2 + into the Zn2 + sites for (La0.95Ca0.05) (Zn1xMnx) SbO. The Hall coefficient measurement indicates p-type carrier for (La0.95Ca0.05) (Zn0.9Mn0.1) SbO with concentration of n ~ 1020 cm3showing anomalous Hall effect below TC.
