Abstract

Abstract—

Experimental studies of magnetic and magnetocaloric properties of polycrystalline RCo₅ alloys (R = Gd, Tb, Dy, Ho) in external magnetic fields up to 3 Tesla have been carried out. The results of magnetic measurements have shown that these compounds have small coercivity and reach saturation in small fields. It was found that the magnetocaloric effect in the studied co-compounds is observed in a wide temperature range, and for the intermetallides TbCo₅, DyCo₅, HoCo₅ has several regions of existence, comparable in magnitude of the effect. The presence of several MCE existence intervals is caused by a series of magnetic phase transitions in these ferrimagnetic compounds.
