The magnetic and magnetocaloric properties of GdInO3 were studied. A reversible magnetocaloric effect was observed, and it showed a large magnetic entropy change and relative cooling power at lower temperatures.
The magnetic and magnetocaloric properties were studied in a stuffed honeycomb polycrystalline antiferromagnet GdInO3. The onset temperature of antiferromagnetic ordering was observed at similar to 2.1 K. Negligible thermal and magnetic hystereses suggest a reversible magnetocaloric effect (MCE) in the GdInO3 compound. In the magnetic field changes of 0 kOe-50 kOe and 0 kOe-70 kOe, the maximum magnetic entropy change values are 9.65 J/kg.K and 18.37 J/kg.K, respectively, near the liquid helium temperature, with the corresponding relative cooling power values of 115.01 J/kg and 211.31 J/kg. The MCE investigation of the polycrystalline GdInO3 serves to illuminate more exotic properties in this frustrated stuffed honeycomb magnetic system.
