Anisotropic exchange interactions in III-V diluted magnetic semiconductors
The RKKY interaction between substitutional Mn local moments in GaAs is both spin-direction dependent and spatially anisotropic. In this paper we address the strength of these anisotropies using a semiphenomenological tight-binding model that treats the hybridization between Mn d-orbitals and As p-orbitals perturbatively and accounts realistically for its nonlocality. We show that valence-band ...
متن کاملExchange interactions and critical temperatures in diluted magnetic semiconductors
A first-principles approach to magnetic properties of diluted magnetic semiconductors (DMS) is presented that is based on the local spin-density approximation (LSDA) as implemented in the framework of the tight-binding linear muffin-tin orbital method, while the effect of randomness is described by the coherent potential approximation. Application of a real-space Greenfunction formalism yields ...
متن کاملX-ray magnetic dichroism in the III-V diluted magnetic semiconductors
Diluted magnetic semiconductors (DMSs) are semiconductors alloyed with magnetic elements [1]. The physical properties of these materials can be tuned by both charge and spin, thus, they have great potential of being used in a wide variety of spintronic applications, such as magneto-optical, magneto-electrical, and magneto-transport devices. Spintronics (spin+electronics) is the technology that ...
متن کاملMagnetic domains in III-V magnetic semiconductors
Recent progress in the theoretical understanding of magnetic anisotropy and stiffness in III-V magnetic semiconductors is exploited for predictions of magnetic domain characteristics and methods of their tuning. We evaluate the width and the energy of domain walls as well as the period of stripe domains in perpendicular films. The computed stripe width W51.1 mm for Ga0.957Mn0.043As/In0.16Ga0.84...
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...
