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_0.55Sr_0.45Mn_1−xCr_xO₃ 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.
