Carrier induced ferromagnetism in the insulating Mn doped III-V semiconductor InP
Richard Bouzerar, Denis Machon, Patrice Melinon +4
Although InP and GaAs have very similar band-structure their magnetic properties appear to drastically differ. Critical temperatures in (In,Mn)P are much smaller than that of (Ga,M…
Unraveling the nature of carrier mediated ferromagnetism in diluted magnetic semiconductors
Georges Bouzerar, Richard Bouzerar
After more than a decade of intensive research in the field of diluted magnetic semiconductors (DMS), the nature and origin of ferromagnetism, especially in III-V compounds is stil…
Spin-wave excitations in presence of nanoclusters of magnetic impurities
Akash Chakraborty, Paul Wenk, Stefan Kettemann +2
Nanoscale inhomogeneities and impurity clustering are often found to drastically affect the magnetic and transport properties in disordered/diluted systems, giving rise to rich and…
Spontaneous magnetization in presence of nanoscale inhomogeneities in diluted magnetic systems
Akash Chakraborty, Paul Wenk, Richard Bouzerar +1
The presence of nanoscale inhomogeneities has been experimentally evidenced in several diluted magnetic systems, which in turn often leads to interesting physical phenomena. Howeve…
Unified picture for diluted magnetic semiconductors
Richard Bouzerar, Georges Bouzerar
For already a decade the field of diluted magnetic semiconductors (DMS) is one of the hottest. In spite of the great success of material specific Density Functional Theory (DFT) to…
Optical conductivity of Mn doped GaAs
Georges Bouzerar, Richard Bouzerar
We study the optical conductivity in the III-V diluted magnetic semiconductor GaMnAs and compare our calculations to available experimental data. Our model study is able to reprodu…
On the reliability of recent Monte Carlo studies of dilute systems of localized spins interacting with itinerant carriers
Richard Bouzerar, Georges Bouzerar
In this paper, we discuss magnetic properties of dilute systems of localized spins interacting with itinerant carriers. More precisely, we compare recent available Monte Carlo resu…
Comment on the PRL "Large-Scale Monte Carlo Study of a Realistic Lattice Model for Ga_(1-x)Mn_xAs"
Georges Bouzerar, Richard Bouzerar
We comment on the recent paper "Large-Scale Monte Carlo Study of a Realistic Lattice Model for Ga_(1-x)Mn_xAs" by Y. Yildirim, G. Alvarez, A. Moreo and E. Dagotto", Phys Rev. Lett.…
Superexchange induced canted ferromagnetism in dilute magnets
Georges Bouzerar, Richard Bouzerar, Olivier Cepas
We argue, in contrast to recent studies, that the antiferromagnetic superexchange coupling between nearest neighbour spins does not fully destroy the ferromagnetism in dilute magne…
Comparison between ab-initio and phenomenological modeling of the exchange couplings in diluted magnetic semiconductors: the case of
Georges ~Bouzerar, Richard Bouzerar, Josef ~Kudrnovský +1
Using a recently developed semi-analytical method (Self-Consistent Local RPA or SC-LRPA) we study the stability of the ferromagnetic phase in diluted magnetic systems where the exc…
