Tuning the magnetic properties of half-metallic semi-Heusler alloys by sp-electron substitution: The case of AuMnSnSb quaternary alloys
K. Ozdogan, I. Galanakis, E. Sasioglu
We study the electronic and magnetic properties of the quaternary AuMnSnSb Heusler alloys using first principles calculations. We determine their magnetic phase diagr…
Kondo resonance in an ac driven quantum dot subjected to finite bias
Ali Goker
We employ the time-dependent non-crossing approximation to study the time averaged conductance for a single electron transistor in the Kondo regime when the dot level is sinusoidal…
Ab-initio determined electronic and magnetic properties of half-metallic NiCrSi and NiMnSi Heusler alloys; the role of interfaces and defects
I. Galanakis, K. Ozdogan, E. Sasioglu
Using state-of-the-art first-principles calculations we study the properties of the ferromagnetic Heusler compounds NiYSi where Y stands for V, Cr or Mn. NiCrSi and NiMnSi contrary…
3d-electron induced magnetic phase transition in half-metallic semi-Heusler alloys
I. Galanakis, E. Sasioglu, K. Ozdogan
We study the effect of the non-magnetic 3\textit{d} atoms on the magnetic properties of the half-metallic (HM) semi-Heusler alloys CoCuMnSb and NiCuMnSb…
