Under 0.01 T applied magnetic field variation, the calculation of magnetocaloric properties for 200 and 800 nm nanotubes of La{sub 0.325}Pr{sub 0.3}Ca{sub 0.375}MnO{sub 3} (LPCMO) perovskite such as magnetic entropy change, full-width at half-maximum (δT FWHM), relative cooling power, and magnetic specific heat change have been done. Magnetocaloric properties of 800-nm nanotubes of LPCMO is more than MCE of 200 nm ones. LPCMO nanotubes have hopeful application for magnetic refrigeration (MR) in an extended high-temperature range due to high values of δT{sub FWHM}. Therefore, nanotubes of LPCMO are very significant for MR applications, especially nitrogen liquefier.
