| Abstract Scope |
This study investigates magnetocaloric materials from the Gd1X1Si1 series, where X = Fe, Co, Mn, with a primary focus on Gd(Fe, Co)1Si, Gd(Mn, Co)1Si, and Gd(Fe, Mn)1Si alloys. Previous research primarily examined the impact of chemical composition on the Curie temperature without addressing adiabatic temperature change. Literature confirms a phase transition near room temperature for Gd(MnCo)1Si and Gd(MnFe)1Si alloys, suggesting their potential for room temperature applications due to the magnetocaloric effect. This detailed investigation involved varying Mn, Fe, and Co contents to study their impact on chemical composition, phase composition, and magnetocaloric properties. The prepared alloys were analyzed for their crystal structure, phase composition, and microstructure. Adiabatic temperature changes were measured for all materials, including Gd(Fe, Co)1Si. These findings contribute to a deeper understanding of the potential application of these alloys in magnetocaloric devices operating at room temperature. |
