Using Density Functional Theory, we have investigated the emergence of half-metallicity in a quaternary Heusler compound with both 3d and 4d electrons as constituents, by chemical substitutions at different sites in the lattice. Mn2RhSi, Co2RhSi and

Employing {\it ab initio} electronic structure calculations we extensively study ternary Heusler compounds having the chemical formula X$_2$X$^\prime$Z, where X = Mn, Fe or Co; Z = Al or Si; and X$^\prime$ changes along the row of 4$d$ transition met
