Motivated by the recent suggestion of anisotropic effective exchange interactions between Mn spins in Ga$_{1-x}$Mn$_x$As (arising as a result of
Research on the exchange bias (EB) phenomenon has witnessed a flurry of activity during recent years, which stems from its
We have obtained new inelastic neutron scattering (INS) data for the molecular magnet Mn12-acetate which exhibit at least six magnetic
An exchange-correlation energy functional $ E_{\mathrm xc} $ and the resultant exchange-correlation potential $ v_{\mathrm xc}({\bf r}) $ in density-functional
We studied the exchange coupling and decoupling occurring in a nanocomposite spin system based on a 3D Heisenberg model by
We explored the magnetic behavior of a common two-phase nanomagnetic system by Monte Carlo computer simulation of a modified Heisenberg
We present results on the exchange cross section for the interaction between a hard binary and a field of single
We study a class of growth processes in which clusters evolve via exchange of particles. We show that depending on
Theory and recent experiments concerning exchange-driven magnetic excitation (EDME) are reviewed. This phenomenon employs the exchange field produced by a
In bulk silicon, intervalley electronic interference has been shown to lead to strong oscillations in the exchange coupling between impurity
We perform inelastic neutron scattering measurements on the molecular nanomagnet Mn_12-acetate to measure the excitation spectrum up to 45meV (500K).
Magnetic properties of a tetrahedral "Ni_4" molecule are discussed in terms of the Heisenberg model, with magnetic anisotropy terms included,
One of the remarkable properties of the II-VI diluted magnetic semiconductor (ZnMn)Se is the giant spin splitting of the valence

We compaWe compare the absorptive corrections to the one pion exchange in $pp\to Xn$ and $ep\to e'Xn$ reactions. It is
The 2D metal-insulator transition can be induced either by decreasing the carrier density or by increasing the spin polarization by
New services based on the best-effort paradigm could complement the current deterministic services of an electronic financial exchange. Four crucial
A review of the approximations in any time-dependent density functional calculation of excitation energies is given. The single-pole approximation for
An internal anisotropy pulse field is launched by an 8.3 ps short laser excitation, which triggers precessional magnetization dynamics of
The domain state model for exchange bias has been further investigated by considering vector spins for the antiferromagnet instead of
An exchange energy functional is proposed and tested for obtaining a class of excited-state energies using density-functional formalism. The functional
Recently it has been predicted that a spin-polarized electrical current perpendicular-to-plane (CPP) directly flowing through a magnetic element can induce
