Materials exhibiting electronic inhomogeneities at the nanometer scale, such as magnetic polarons, have great potential for magnetoresistive applications. Here, thermal expansion and magnetostriction measurements on Eu5In2Sb6 single crystals reveal the formation of magnetic polarons well above the magnetic ordering temperature, providing insights on colossal magnetoresistive behavior beyond manganites.
