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…
Exchange couplings for Mn ions in CdTe: validity of spin models for dilute magnetic II-VI semiconductors
Thorben Linneweber, Jörg Bünemann, Ute Löw +2
We employ density-functional theory (DFT) in the generalized gradient approximation (GGA) and its extensions GGA+ and GGA+Gutzwiller to calculate the magnetic exchange couplings…
Interplay of Coulomb interaction and spin-orbit coupling
Jörg Bünemann, Thorben Linneweber, Ute Löw +2
We employ the Gutzwiller variational approach to investigate the interplay of Coulomb interaction and spin-orbit coupling in a three-orbital Hubbard model. Already in the paramagne…
Magnetization, Magnetic Susceptibility and ESR in Tb3Ga5O12
U. Löw, S. A. Zvyagin, M. Ozerov +4
We report on the measurement of the magnetic susceptibility and of ESR transitions in the garnet substance TbGaO (TGG). The results are compared with a calculation i…
Acoustic Faraday effect in TbGaO
A. Sytcheva, U. Loew, S. Yasin +5
The transverse acoustic wave propagating along the [100] axis of the cubic TbGaO (acoustic mode) is doubly degenerate. A magnetic field applied in the direc…
Finite size effects and magnetic order in the spin-1/2 honeycomb lattice compound InCu{2/3}V{1/3}O{3}
M. Yehia, E. Vavilova, A. Moeller +5
High field electron spin resonance, nuclear magnetic resonance and magnetization studies addressing the ground state of the quasi two-dimensional spin-1/2 honeycomb lattice compoun…
Dynamical structure factor of the anisotropic Heisenberg chain in a transverse field
J. S. Caux, F. H. L. Essler, U. Loew
We consider the anisotropic Heisenberg spin-1/2 chain in a transverse magnetic field at zero temperature. We first determine all components of the dynamical structure factor by com…
High Magnetic Field ESR in the Haldane Spin Chains NENP and NINO
M. Sieling, U. Löw, B. Wolf +3
We present electron spin resonance experiments in the one-dimensional antiferromagnetic S=1 spin chains NENP and NINO in pulsed magnetic fields up to 50T. The measured field depend…
Dynamic correlations of antiferromagnetic spin-1/2 XXZ chains at arbitrary temperature from complete diagonalization
Klaus Fabricius, Ute Löw, Joachim Stolze
All eigenstates and eigenvalues are determined for the spin- 1/2 chain for rings w…
