Spin currents in diluted magnetic semiconductors.
We study zero-bias spin separation in (Cd,Mn)Te/(Cd,Mg)Te diluted magnetic semiconductor structures. The spin current generated by electron gas heating under terahertz radiation is converted into a net electric current by applying an external magnetic field. The experiments show that the spin polarization of the magnetic ion system enhances drastically the conversion process due to giant Zeeman...
متن کاملANALYSIS OF SOME MAGNETIC PROPERTIES OF DILUTED MAGNETIC SEMICONDUCTORS
The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...
متن کاملAtomistic spin model simulations of magnetic nanomaterials.
Atomistic modelling of magnetic materials provides unprecedented detail about the underlying physical processes that govern their macroscopic properties, and allows the simulation of complex effects such as surface anisotropy, ultrafast laser-induced spin dynamics, exchange bias, and microstructural effects. Here we present the key methods used in atomistic spin models which are then applied to...
متن کاملSuppression of electron spin relaxation in Mn-doped GaAs.
We report a surprisingly long spin relaxation time of electrons in Mn-doped p-GaAs. The spin relaxation time scales with the optical pumping and increases from 12 ns in the dark to 160 ns upon saturation. This behavior is associated with the difference in spin relaxation rates of electrons precessing in the fluctuating fields of ionized or neutral Mn acceptors, respectively. For the latter, the...
