A first-principles comparison of the electronic properties of MgC_{y}Ni_{3} and ZnC_{y}Ni_{3} alloys
P. Jiji Thomas Joseph, Prabhakar P. Singh
First-principles, density-functional-based electronic structure calculations are employed to study the changes in the electronic properties of ZnC_{y}Ni_{3} and MgC_{y}Ni_{3} using…
Is Delta_{pi}-gap-only superconductivity possible in Mg_{1-x}Al_{x}B_{2} and Mg(B_{1-y}C_{y})_{2} alloys?
P. Jiji Thomas Joseph, Prabhakar P. Singh
Using density-functional-based method, we study the k-resolved sigma- and pi-band holes in Mg_{1-x}Al_{x}B_{2} and Mg(B_{1-y}C_{y})_{2} alloys. We find that the calculated profiles…
Mn and Fe Impurities in MgB_{2}
P. Jiji Thomas Joseph, Prabhakar P. Singh
Based on first principles calculations, we show that impurities are magnetic in due to exchange-splitting of band and they substantially modify $p_σ…
Compositional disorder and its influence on the structural, electronic and magnetic properties of MgC(Ni_{1-x}Co_{x})_{3} alloys using first-principles
P. Jiji Thomas Joseph, Prabhakar P. Singh
First-principles, density-functional based electronic structure calculations are carried out for MgC(Ni_{1-x}Co_{x})_{3} alloys over the concentration range 0\leq x\leq1, using Kor…
Incipient magnetism in the cubic perovskites MgCNi3 and YBRh3: A comparison
P. Jiji Thomas Joseph, Prabhakar P. Singh
Using density-functional-based methods, we have studied the effects of incipient magnetism in the cubic perovskites MgCNi_{3} and YBRh_{3} . Our results show that (i) at the equili…
On the propensity of magnetism in 3d transition-metal-MgCNi_3 alloys
P. Jiji Thomas Joseph, Prabhakar P. Singh
The changes in the electronic properties of the substitutionally disordered MgC(Ni_{1-x}T_{x})_{3} (T=Fe, Co or Cu) alloys are studied using the atomic sphere formulation of the Ko…
