Sol–gel technique is low cost, simple and easy to handle.

Our samples crystallize in the rhombohedric symmetry with the $R\overline{3}c$ space group.

The samples exhibit PM-FM phase transition at T_C.

T_C decreases with increasing In content from 310 K for x = 0.00 to 251 K for x = 0.10.

The magnetocaloric effect is studied and the $-\Delta {\mathrm{S}}_{\mathrm{M}}^{\max }$ and RCP are determined.
