Sol–gel technique is low cost, simple and easy to handle.
Our samples crystallize in the rhombohedric symmetry with the JSB inlineImage" height="14" width="26" alt="View the MathML source" style="margin-top: -5px; vertical-align: middle" title="View the MathML source" src="/sd/grey_pxl.gif" data-inlimgeid="1-s2.0-S0925838816326688-si1.gif"> space group.
The samples exhibit PM-FM phase transition at TC.
TC 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 and RCP are determined.
