The first measurements of elastic constants, together with resistivity, of both unstrained and strained colossal magnetoresistance (CMR) material in the form of thin films on a substrate are reported. Briefly, the results show that changes in the elastic constants occur at the temperature of peak resistance, which decreases as the film thickness decreases. Furthermore, changes in the elastic constants are also observed at temperatures about 17K higher than the peak resistance temperature, which is a new result for the CMR material studied.
