Berry phase, topology, and diabolicity in quantum nano-magnets
Patrick Bruno
A topological theory of the diabolical points (degeneracies) of quantum magnets is presented. Diabolical points are characterized by their diabolicity index, for which topological…
Equilibrium spin currents and magnetoelectric effect in magnetic nanostructures
Patrick Bruno, Vitalii K. Dugaev
We discuss the problem of equilibrium spin currents in ferromagnets with inhomogeneous magnetization. Using simple microscopic models we explain the physical origin of equilibrium…
Exchange interactions and temperature dependence of the magnetization in half--metallic Heusler alloys
E. Sasioglu, L. M. Sandratskii, P. Bruno +1
We study the exchange interactions in half-metallic Heusler alloys using first-principles calculations in conjunction with the frozen-magnon approximation. The Curie temperature is…
Berry phase effects in magnetism
Patrick Bruno
Lecture notes published in ''Magnetism goes nano'', Lecture Manuscripts of the 36th Spring School of the Institute of Solid State Research, edited by Stefan Bluegel, Thomas Bruecke…
Magnetic exchange coupling and Curie temperature of Ni(1+x)MnSb (x=0, 0.25, 0.5, 0.75, 1) from first principles
E. Sasioglu, L. M. Sandratskii, P. Bruno
We study the dependence of magnetic interactions and Curie temperature in Ni(1+x)MnSb system on the Ni concentration within the framework of the density-functional theory. The calc…
Pressure dependence of the Curie temperature in Ni2MnSn Heusler alloy: A first-principles study
E. Sasioglu, L. M. Sandratskii, P. Bruno
The pressure dependence of electronic structure, exchange interactions and Curie temperature in ferromagnetic Heusler alloy Ni2MnSn has been studied theoretically within the framew…
