Being a wide band gap system GaMnN attracted considerable interest after the discovery of highest reported ferromagnetic transition temperature $T_C$ $\sim$ 940 K among all diluted magnetic semiconductors. Later it become a debate due to the observat

Large magnetoresistive materials are of immense interest for a number of spintronic applications by developing high density magnetic memory devices, magnetic sensors and magnetic switches. Colossal magnetoresistance, for which resistivity changes sev

We investigate the ultra-sharp jump in the isothermal magnetization and the resistivity in the polycrystalline Sm0.5(Ca0.5−ySry)MnO3(y = 0, 0.1, 0.2, 0.25, 0.3, 0.5) compounds. The critical field (Hcr), required for the ultra-sharp jump, decreases

We design reversible multi-level resistance states in a half-doped charge-ordered manganite, (SCSMO). By exploiting the electronic phase separation in SCSMO at 10 K, we show that the system can be stabilized into several metastable states, against th

We have investigated the effect of Ti doping on the transport properties coupled with the magnetic ones in ${\mathrm{Sm}}_{0.55}{\mathrm{Sr}}_{0.45}{\mathrm{Mn}}_{1\ensuremath{-}\ensuremath{\eta}}{\mathrm{Ti}}_{\ensuremath{\eta}}{\mathrm{O}}_{3}\phan

We investigate the magnetic and the transport properties of diluted magnetic semiconductors using a spin-fermion Monte-Carlo method on a 3D lattice in the intermediate coupling regime. The ferromagnetic transition temperature $T_c$ shows an optimizat

Using density functional theory based calculations, we have systematically studied the equilibrium geometries, relative stabilities, and electronic and magnetic properties of Fe and Mn atoms interacting with a varying number of BO(2) moieties. These

Using density functional theory with generalized gradient approximation for exchange and correlation potential we show that the magnetic coupling between Mn atoms in Mn 2 Cl n molecular systems can be manipulated not only by varying the number of Cl
