Abstract

This study explores critical phenomena (CEs) in amorphous Gd₅₂Fe₂₈B₂₀ near its temperature at which the transition occurs from the ferromagnetic (FM) phase to the paramagnetic (PM) phase. Sample was synthesized using the melt spinning process. Our analysis reveals a second-order (SO) magnetic phase transition from FM state to PM state. We employed various well-established techniques to determine the value of critical exponents, including the modified Arrott plot (MAP), critical isotherm analysis (CIA), Widom scaling relation (WSR), and Kouvel-Fisher (KF). Additionally, separate investigation of the critical behavior was analyzed through the connexion with phenomenon is known as magnetocaloric effect (MCE) yielding results consistent with the analysis of magnetization data. The obtained critical exponent values exhibit consistency and comparability with predictions from the mean field (MF) theory. Finding results emphasis, the presence of long-range FM exchange interactions within the material.

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.
