dc.description.abstract
We have measured the magnetic field dependence of the anelastic modulus and the electric resistance of a ceramic sample of the magnetoresistant perovskite La2/3Ca1/3MnO3 around the metal-insulator transition by the vibrating reed technique (2.5 KHz). Previous work showed that the modulus becomes higher while the internal friction has a peak at the transition temperature (Tc = 262 K). In this work, improvements made on the equipment allowed us to measure at constant deformations (ε<105) and magnetic fields up to 4500 Gauss. We made isothermal measurements of internal friction, modulus and resistance as a function of an applied magnetic field. We found that most of the changes induced by the magnetic field take place in a few degrees (almost 5 K) near the transition temperature where the changes in resistance are more important. Up to the highest magnetic field applied, we found 3% maximum variations of the modulus and no hysteresis while cycling the magnetic field. We suppose that the experiment is placed in the linear response of the inverse Wiedemann effect, due to the small deformations used, and that the ferromagnetic domain structure is responsible for the observed effects. Some additional measurements are needed (magnetic hysteresis loops) to be compared with our results.
