Abstract

IV-VI materials doping with magnetic impurities presents exciting opportunities for spintronic applications particularly by incorporating the memory component in the semiconducting matrix. The proposed work investigates carrier mediated magnetic interactions in GeTe lattice alloyed with Mn ions. We present Ge_1-x-ySi_xMn_yTe bulk crystals having a chemical composition of Si, x = 0.057, 0.053 and Mn, y = 0.035, 0.041 to explore the dominant magnetic interactions in these crystals. The results show that magnetic phase transition temperature for both crystals is closer to 170 K, with the Curie-Weiss temperature (

θ

) calculated as 171 K for y = 0.035 and 172.8 K for y = 0.041, indicating ferromagnetic-like interactions amongst Mn ions. An increase in Mn content from y = 0.035 to 0.041, the maxima of susceptibility cusp amplify about an order of magnitude. Modified Curie-Weiss law fits on susceptibility inverse finds ferromagnetic-like interaction in the alloys. Additionally, high field magnetization data was used for calculating the number of active magnetic ions in semiconductor matrix.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
