Investigation of the Hall and Nernst-Ettingshausen Effects in Diluted Magnetic Semiconductors
Abstract: This review explores the Hall and Nernst-Ettingshausen effects in various magnetic systems, including diluted magnetic semiconductors (DMS), topological insulators, superconductors, and novel composite materials. In DMS, the interplay of ferromagnetism and magnetic impurities introduces unique transport behaviors, particularly influencing the anomalous Hall effect (AHE) and thermomagnetic phenomena. We also examine the Nernst-Ettingshausen effect (NE) in topological insulators and superconductors, revealing the influence of band topology and vortex-like excitations. Special attention …

Ferromagnetic Resonance in II-VI Diluted Magnetic Semiconductor, ZnxTM1-xO Nanostructures
Abstract: The ferromagnetic resonance in II-VI diluted magnetic semiconductor Zn1 xMnxO was studied theoretically. The model employed to manipulate the Hamiltonian of the system which is the Heisenberg Model. By considering a cloud of electron gas and employing equation of state, the fractions of demagnetization factors was determined. For FMR probes, the sample magnetization results from the magnetic moments of dipolar-coupled but unpaired electrons. The resulting frequency versus magnetization curve is …
