Theoretical modeling reveals spin dynamics and linear Néel temperature dependence in manganese-doped zinc telluride, highlighting mechanisms for spin-optoelectronic devices.
The interaction between the optical, electrical and magnetic properties of diluted magnetic semiconductors (DMSs) is of fundamental interest and may enable future spin-optoelectronic devices. In order to enable to them useful for such devices efforts have been made to develop diluted magnetic semiconductors (DMS) in which small quantity of magnetic ion is introduced in to normal semiconductors. with face centered cubic structure and long-range antiferromagnetic ordering is investigated within the frame work of the Heisenberg model. The Hamiltonian includes exchange interactions with the nearest neighbors and Zeeman terms. Calculations are performed using Holstein-Primakoff transformation and Green’s function formalism. By using these techniques and model, we examine excited total number of magnon, equation of motion, dispersion relation, Temperature dependencies of reduced magnetization and linear concentration dependence of Neel temperature is also predicted.
