Study of solid-state synthesized Pr 0.55 Sr 0.45 Mn 1− x Cr x O 3 perovskites with x = 0.0, 0.05, 0.1 and 0.15: Rietveld analysis and magnetic and magnetocaloric properties for magnetic refrigeration applications
Key Points
The research aims to investigate the magnetic and magnetocaloric properties of Pr<sub>0.55</sub>Sr<sub>0.45</sub>Mn<sub>1−x</sub>Cr<sub>x</sub>O<sub>3</sub> perovskites.
Solid-state synthesis of perovskites with varying chromium content (x=0.0, 0.05, 0.1, 0.15)
Conducted Rietveld analysis to assess crystalline structure and magnetic properties
Evaluated magnetocaloric properties for applicability in magnetic refrigeration.
The perovskite with 5% chromium demonstrated 58% of the RCP (refrigerant capacity) value compared to gadolinium metal.
Abstract
(5% of chromium) was equivalent to 58% of the RCP value of gadolinium metal. Technically, the developed material is highly promising for magnetic refrigeration because of these significant values.
