Abstract
In this study, we report on the preparation and magnetocaloric properties of Dy2Ru2O. Our investigation reveals that the system exhibits crucial characteristics for becoming a promising magnetocaloric material at low temperatures, including significantly high saturation magnetization. The magnetocaloric effect at low temperatures is substantially large, with a magnetic entropy change () of 10.15 J Kg−1 K−1 for a field change of 20 kOe at 4 K, reaching a maximum of 15.08 J Kg−1 K−1 for a field change of 70 kOe at 6 K. Additionally, the material is expected to demonstrate strong efficiency across a broad temperature range of at least 10 K. These findings suggest that Dy2Ru2O is an excellent candidate for low-temperature magnetic refrigeration, particularly suitable for applications near cryogenic temperatures, including liquid helium temperature.
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.
