Ph.D. Dissertation:
I have studied the electronic and magnetic properties of transition metal based Heusler compounds by using the density functional theory (DFT). A DFT relies upon the Kohn-Sham (KS) equation with inclusion of exchange-correlation potential to improve the accuracy. The most commonly used exchange-correlation functional are generalized gradient approximation (GGA-PBE, Perdew, Burke and Ernzerhof), local (spin) density approximation LDA/LSDA, modified Becke Johnson (mBJ) potential, etc. Magnetic properties are natural outputs of the calculations and itinerant magnetism can be discussed in a more qualitatively. The more relevant method LSDA+U (Coulomb repulsion) formalism is used to treat the strongly correlated electrons for better accuracy of the ground state properties. A code Wien2k based on full potential linearized augmented plane wave (FP-LAPW) method within DFT is adopted. We mainly focus on the half-metallicity (HMF) of L21 type full Heusler alloys with formula X2YZ (X,Y = Sc, Ti, V, Mn, Fe, Co and Z = Al, Si, Ga, Ge, As, etc).
