Effect of Doping on Van der Waals Cr-Based Materials

Among the most interesting emerging fields in magnetism and its applications are the magnetocaloric effect (MCE) and spintronics. The interest is largely inspired by its potential application in near room temperature applications in refrigeration, data storage, the sensing device, and switching circuits. For example, the new refrigeration system is expected to replace the conventional expansion-compression refrigerators. One of the main challenges is to develop low-cost materials with cooling efficiency matching or exceeding the efficiency of the conventional refrigerators. The prototype material for magnetic refrigeration is the expensive elemental gadolinium, which exhibits one of the largest known MCEs near room temperature. In this study, we aim to develop a new material that combines most of the desired properties for room temperature applications. These properties include low cost, high chemical stability, high cooling power, low hysteresis losses, low eddy current losses, easily magnetized material with high magnetization that operates near room temperature and are stable over a wide range of temperatures. In particular; we are going to investigate the effects of doping on the critical behavior and structure of Van der Waals Cr-based materials to be used in such applications.
