| ErMn2 Laves phase Melt spun ribbons Magnetocaloric effect Magnetic entropy change Adiabatic temperature change | |
| "We have fabricated melt-spun ribbons of nominal composition ErMn2 and studied their phase constitution and magnetocaloric (MC) properties by X-ray diffraction, scanning electron microscopy (SEM), magnetization and heat capacity measurements. The major phase formed shows the MgZn2-type hexagonal structure (C14-type); however, both XRD and SEM analyses revealed the formation of impurity phases (i.e., Er6Mn23 and ErMn12). Ribbons exhibit a saturation magnetization of 149 Am2kg?1 at 2 K and a Curie temperature of TC = 15 K. A field-induced metamagnetic transition at very low critical magnetic fields was observed below 8 K that leads to a change of sign in the magnetic entropy change ?SM below this temperature (?SMpeak = 2.5 Jkg?1K?1 at 2 K and 5 T). For a magnetic field change of 5 T (2 T) applied along the ribbon length, the samples show a large peak value of the magnetic entropy change ?SMpeak of ?20.5 (?10.8) Jkg?1K?1, a full-width at half-maximum ?TFWHM for the ?SM(T) curve of 20 (12) K, and a maximum adiabatic temperature change ?Tadmax of 7.4 (3.6) K. The obtained results are compared with the reported in literature by other authors for bulk alloys." | |
