Magnetocaloric effect on nanocrystalline melt spun R2Fe17 (R= Pr, Nd) ribbons

Abstract

R2Fe17 intermetallic alloys, specifically those with R= Pr and Nd undergo second-order magnetic phase transition with Curie temperatures close to room temperature. These alloys exhibit a notorious broad magnetocaloric effect (MCE), rendering them exceptionally promising for diverse applications, including the burgeoning field of vibrational/mechanical energy-harvesting. The fabrication of these alloys into ribbon shape not only enhances their versatility, unlocking a spectrum of potential uses in various technological domains, but also reduces both economic and ecological processing costs by avoiding lengthy annealing processes during manufacturing.
