Coexistence of low and high spin states in La$_{18}$Co$_{28}$Pb$_{3}$
Coexistence of low and high spin states in La$_{18}$Co$_{28}$Pb$_{3}$
The electronic structure and magnetic properties of a newly predicted stable ternary compound La$_{18}$Co$_{28}$Pb$_{3}$ are studied using electronic structure analysis. The ground state of this compound is ferromagnetic, with three positions of nonequivalent magnetic Co atoms. A strong dependence of magnetic properties on volume shows that this system is situated …
