Metallic magnetism at finite temperatures studied by relativistic disordered moment description: Theory and applications
A. Deák, E. Simon, L. Balogh +3
We develop a self-consistent relativistic disordered local moment (RDLM) scheme aimed at describing finite temperature magnetism of itinerant metals from first principles. Our impl…
Spin-correlations and magnetic structure in an Fe monolayer on 5d transition metal surfaces
E. Simon, K. Palotás, B. Ujfalussy +3
We present a detailed first principles study on the magnetic structure of an Fe monolayer on different surfaces of 5d transition metals. We use the spin-cluster expansion technique…
Exchange Bias driven by Dzyaloshinskii-Moriya interactions
R. Yanes, J. Jackson, L. Udvardi +2
The exchange bias effect in compensated IrMn3/Co(111) system is studied using multiscale modeling from "ab initio" to atomistic calculations. We evaluate numerically the out-of-pla…
Thickness-dependent magnetic structure of ultrathin Fe/Ir(001) films: from spin-spiral states towards ferromagnetic order
A. Deák, L. Szunyogh, B. Ujfalussy
We present a detailed study of the ground-state magnetic structure of ultrathin Fe films on the surface of fcc Ir(001). We use the spin-cluster expansion technique in combination w…
Magnetic anisotropy of FePt: effect of lattice distortion and chemical disorder
C. J. Aas, L. Szunyogh, J. S. Chen +1
We perform first principles calculations of the magnetocrystalline anisotropy energy in the five L10 FePt samples studied experimentally by Ding et al. [J. App. Phys. 97, 10H303 (2…
Ab initio study of canted magnetism of finite atomic chains at surfaces
B. Lazarovits, B. Ujfalussy, L. Szunyogh +2
By using ab initio methods on different levels we study the magnetic ground state of (finite) atomic wires deposited on metallic surfaces. A phenomenological model based on symmetr…
Limitations of the two-media approach in calculating magneto-optical properties of layered systems
A. Vernes, L. Szunyogh, P. Weinberger
It is shown that in polar geometry and normal incidence the 2x2 matrix technique - as discussed in detail in a preceeding paper [Phys. Rev. B 65, 144448 (2002)] - accounts correctl…
Fully relativistic calculation of magnetic properties of Fe, Co and Ni adclusters on Ag(100)
B. Lazarovits, L. Szunyogh, P. Weinberger
We present first principles calculations of the magnetic moments and magnetic anisotropy energies of small Fe, Co and Ni clusters on top of a Ag(100) surface as well as the exchang…
Numerically improved computational scheme for the optical conductivity tensor in layered systems
A. Vernes, L. Szunyogh, P. Weinberger
The contour integration technique applied to calculate the optical conductivity tensor at finite temperatures in the case of layered systems within the framework of the spin-polari…
Theory of the Fano Resonance in the STM Tunneling Density of States due to a Single Kondo Impurity
O. Újsághy, J. Kroha, L. Szunyogh +1
The conduction electron density of states nearby single magnetic impurities, as measured recently by scanning tunneling microscopy (STM), is calculated, taking into account tunneli…
