Article Description

The magnetocaloric effect (MCE) of LaSrMnO (LSMO) nanofibers (NFs) is analyzed using a phenomenological model. It is concluded that a low magnetic field change (ΔH determines the shape of magnetic entropy change curves. This directly has an effect on the values of specific heat, relative cooling power and temperature changes. Therefore, ΔH is an effective control of MCE for the LSMO NFs. Consequently, the LSMO NFs are useful as practical refrigerant materials working in relatively low ΔH. This advantage makes the LSMO NFs potentially practical refrigerant materials for efficient cooling devices. In addition, the MCE of LSMO NFs is significantly larger and comparable with the MCE of other materials like GeMn, LaCdMnO, and GdCaBaCoO.
