“…In order to evaluate the magnetic cooling efficiency one may apply the so-called relative cooling power RCP, which takes into account the width of a temperature interval [41]. We can then consider the magnitude of M ǻS and its full width at half-maximum, known as RCP, given by Pecharsky and Gschneidner [41,42]: than that of several manganites systems with multi-element substitutions at B-sites [43].This material is encouraging enough to pave the way for investigations of materials useful for magnetic cooling with excellent performance and can thus be used as an active magnetic refrigerator materials suggested by Barclay [44].…”
