Magnetic properties and magnetocaloric effect of a metallic triangular lattice antiferromagnetic DyAl2Ge2 single crystal

Magnetocaloric effect modeling of dysprosium-transition metal based intermetallic alloys for magnetic refrigeration application using hybrid genetic algorithm based support vector regression intelligent method

“…The predictors to the models include the applied field, ionic radius of the transition metal and that of other incorporated metals or non-metals. Expression presented in Eq (11) shows the dysprosium -transition metal based magnetocaloric compounds that can be fed into the proposed GSVR based models for maximum magnetic entropy change prediction.…”

“…Where Dy is the rare earth dysprosium, T and X are the transition metal and other incorporated metal or non-metal, respectively. The concentration of dysprosium, transition metal and other incorporated metals or non-metal are respectively represented as a,b and c in expression shown in Eq (11). Statistical investigation was conducted on the dysprosium -transition metal based intermetallic compounds and the results of the analysis are presented in Table 1.…”

“…This leads to change in temperature of the magnetic materials and the process of the temperature or entropy change due to applied field is referred to as magnetocaloric effect [7]. Recent research areas focused on developing magnetic materials with huge magnetocaloric effect for this technology [8][9][10][11][12]. Although, virtually all magnetic materials exhibit magnetocaloric effect while the magnetism of the magnetic materials and magnetic transition phase drive the strength of the exhibited magnetocaloric effect.…”
