| Abstract: | By simulating the thermomagnetization of Ba(Fe1-xScx)12O19 from approximately 100 to 750 K, the magnetocaloric effect (MCE) in Ba(Fe1-xScx)12O19 samples is approximated. Intriguingly, the thermomagnetic property of the undoped sample BaFe12O19 is described as a conventional MCE for high temperatures. However, at doping levels x of 0.128, 0.153, and 0.189, respectively, the thermomagnetic property of Sc-doped samples is defined as an inverse MCE below temperatures of 163, 239, and 318 K. In contrast, thermomagnetic property of Ba(Fe1-xScx)12O19 is described as conventional MCE above those temperatures. Additionally, Sc doping makes it possible for MCE in Ba(Fe1-xScx)12O19 to be strongly tailored. This is helpful for operating a magnetic refrigerator (MR) which occurs in various temperature ranges and results in a higher working temperature range. A promising function for Ba(Fe1-xScx)12O19 samples in MR at high-temperature applications in the automotive and food industries or aerospace. [ABSTRACT FROM AUTHOR] |
