Exploiting of magnetocaloric effect from manganese doped cobalt ferrite nanoparticles for low temperature applications
Journal Title: Invention Journal of Research Technology in Engineering & Management - Year 2018, Vol 2, Issue 12
Abstract
This paper reports on the magnetocaloric effect exploited from the manganese doped cobalt ferrite nanoparticles using indirect method. The optimum values of magnetic entropy change, adiabatic temperature change, refrigeration capacity and maximum specific cooling energy are found to be -0.37J kg -1K -1 , 65.01K, 24.05 J kg -1and 192.95J kg -1 under the magnetic field difference 0.2 T between 0.2 – 0.4 T below 200 K temperature range. As such the investigated materials are expected to be suitable for the applications in low temperature physics and also promising for space born applications
