Graphene in periodically alternating magnetic field: unusual quantization of the anomalous Hall effect
M. Taillefumier, V. K. Dugaev, B. Canals +2
We study the energy spectrum and electronic properties of graphene in a periodic magnetic field of zero average with a symmetry of triangular lattice. The periodic field leads to f…
Magnetic Anistropy due to the Casimir Effect
G. Metalidis, P. Bruno
We consider the Casimir interaction between a ferromagnetic and a non-magnetic mirror, and show how the Casimir effect gives rise to a magnetic anisotropy in the ferromagnetic laye…
Manipulating magnetism and conductance of an adatom-molecule junction on metal surfaces: ab initio study
Kun Tao, V. S. Stepanyuk, P. Bruno +4
The state of the art ab initio calculations reveal the effect of a scanning tunnelling microscopy tip on magnetic properties and conductance of a benzene-adatom sandwich on Cu(001)…
Size-dependent Surface States on Strained Cobalt Nanoislands on Cu(111)
M. V. Rastei, B. Heinrich, L. Limot +4
Low-temperature scanning tunneling spectroscopy over Co nanoislands on Cu(111) showed that the surface states of the islands vary with their size. Occupied states exhibit a sizeabl…
Green's function technique for studying electron flow in 2D mesoscopic samples
G. Metalidis, P. Bruno
In a recent series of scanning probe experiments, it became possible to visualize local electron flow in a two-dimensional electron gas. In this paper, a Green's function technique…
On-site Coulomb interaction and the magnetism of (GaMn)N and (GaMn)As
L. M. Sandratskii, P. Bruno, J. Kudrnovský
We use the local density approximation (LDA) and LDA+U schemes to study the magnetism of (GaMn)As and (GaMn)N for a number of Mn concentrations and varying number of holes. We show…
Electronic structure, exchange interactions and Curie temperature in diluted III-V magnetic semiconductors: (GaCr)As, (GaMn)As, (GaFe)As
L. M. Sandratskii, P. Bruno
We complete our earlier (Phys. Rev. B, {\bf 66}, 134435 (2002)) study of the electronic structure, exchange interactions and Curie temperature in (GaMn)As and extend the study to t…
Disorder effects in diluted ferromagnetic semiconductors
G. Bouzerar, J. Kudrnovsky, P. Bruno
Carrier induced ferromagnetism in diluted III-V semi-conductor is analyzed within a two step approach. First, within a single site CPA formalism, we calculate the element resolved…
The Magnetic Casimir Effect
G. Metalidis, P. Bruno
The Casimir effect results from alterations of the zero-point electromagnetic energy introduced by boundary-conditions. For ferromagnetic layers separated by vacuum (or a dielectri…
RPA-CPA theory for magnetism in disordered Heisenberg binary systems with long range exchange integrals
G. Bouzerar, P. Bruno
We present a theory based on Green's function formalism to study magnetism in disordered Heisenberg systems with long range exchange integrals. Disordered Green's function are deco…
Long-range magnetic interaction due to the Casimir effect
P. Bruno
The zero-point quantum fluctuations of the electromagnetic field in vacuum are known to give rise to a long-range attractive force between metal plates (Casimir effect). For ferrom…
Anomalous Hall effect and weak localization corrections in a ferromagnet
A. Crépieux, J. Wunderlich, V. K. Dugaev +1
In this paper, we report results on the anomalous Hall effect. First, we summarize analytical calculations based on the Kubo formalism : explicit expressions for both skew-scatteri…
Absence of spontaneous magnetic order at non-zero temperature in one- and two-dimensional Heisenberg and XY systems with long-range interactions
Patrick Bruno
The Mermin-Wagner theorem is strengthened so as to rule out magnetic long-range order at T>0 in one- or two-dimensional Heisenberg and XY systems with long-range interactions decre…
Localization corrections to the anomalous Hall effect in a ferromagnet
V. K. Dugaev, A. Crepieux, P. Bruno
We calculate the localization corrections to the anomalous Hall conductivity related to the contribution of spin-orbit scattering into the current vertex (side-jump mechanism). We…
Theory of the anomalous Hall effect from the Kubo formula and the Dirac equation
A. Crépieux, P. Bruno
A model to treat the anomalous Hall effect is developed. Based on the Kubo formalism and on the Dirac equation, this model allows the simultaneous calculation of the skew-scatterin…
Weak localization in ferromagnets with spin-orbit interaction
V. K. Dugaev, P. Bruno, J. Barnas
Weak localization corrections to conductivity of ferromagnetic systems are studied theoretically in the case when spin-orbit interaction plays a significant role. Two cases are ana…
Relativistic corrections in magnetic systems
A. Crépieux, P. Bruno
We present a weak-relativistic limit comparison between the Kohn-Sham-Dirac equation and its approximate form containing the exchange coupling, which is used in almost all relativi…
Range dependence of interlayer exchange coupling
Peter M. Levy, Sadamichi Maekawa, Patrick Bruno
We have considered the effects of non magnetic impurities and interface roughness on the interlayer coupling between magnetic layers in metallic multilayers. The two types of defec…
