Magnetic quenching of time-reversed light in photorefractive diluted magnetic semiconductors
نویسندگان
چکیده
Magnetic fields selectively quench phase conjugation during photorefractive four-wave mixing experiments in the diluted magnetic semiconductor Cd12xMnxTe. Phase conjugation using circularly polarized light fields differentiates between the time-reversed and non-time-reversed components of the four-wave mixing signal. The experimental results establish the connection between the removal of time-reversal symmetry in the solid state by magnetic fields and the magnetic-field-induced quenching of time-reversed phase-conjugate light. @S0163-1829~98!08739-6#

Scattering mechanism of nonmagnetic phase on nano diluted magnetic semiconductors (DMS)
This paper shows the scattering mechanism at diluted magneticsemiconductors. The doped magnetic atom produces a scattering potential due to becoupled of itinerant carrier spin of host material with magnetic momentum of the dopedmagnetic atom. Formulas of scattering event were rewritten by the plane waveexpansion and then the electron mobility of DMS was calculated. Calculations showKondo effect...

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...

Relaxation of thermal-remanent magnetization and isothermal remanent magnetization of spin glass in Cd& „Mn„Te diluted magnetic semiconductors have been studied at different conditions. Magnetization relaxation can be described by a power-law decay, M(t) =Mpt (f & to and to=2 s) with small values of a or a logarithmic decay M(t}=MD(1—a lnt) (t & to and to=2 s). Temperature and applied magnetic-...
متن کاملCoherently photoinduced ferromagnetism in diluted magnetic semiconductors.
Ferromagnetism is predicted in undoped diluted magnetic semiconductors illuminated by intense sub-band-gap laser radiation. The mechanism for photoinduced ferromagnetism is coherence between conduction and valence bands induced by the light which leads to an optical exchange interaction. The ferromagnetic critical temperature T(C) depends both on the properties of the material and on the freque...
