Advanced Materials for Room Temperature Magnetic Refrigeration
Project funded by Babeș-Bolyai University, Cluj-Napoca, Romania
Grant number: GTC-35279/18.11.2020
Duration: 18.11.2020 - 17.11.2021
Total budget: 50000 lei
Project director: Lect. Dr. Ing. Sever Mican
Project summary: In this project we aim to study the theoretical and experimental structural, electronic, magnetic and magnetocaloric properties of rare-earth-3d transition metal intermetallic compounds where we either have a doping of the rare-earth, the transition metal, or both. By controlling the dopant concentration, the transition temperatures of these compounds can be adjusted into the room temperature range, while at the same time enhancing or at least maintaining their magnetocaloric properties. The first objective is to perform a comprehensive theoretical study of the structural, electronic and magnetic properties of rare-earth-3d transition metal intermetallic compounds using Density Functional Theory (DFT), atomistic and mean-field simulations. The second objective is the synthesis of the studied compounds and the experimental investigation of their structural, magnetic and magnetocaloric properties.
