Vous trouverez ici le papier de Michel Boudard, Voici l'abstract:
"We have investigated both temperature and magnetic field dependences of the resistivity of Nd0.67Ba0.33Mn0.98Fe0.02O3 perovskite. Electrical-resistivity measurement in the temperature range 5 - 230 K shows a metal e semiconductor transition at peak temperature, TMS, which shifts to higher temperature when the magnetic field increases. At a field of 7 T the sample presents a large magneto-
Results show that the as obtained magnetic entropy change values are similar to those determined using data obtained from the investigation of temperature and magnetic field dependences of magnetization.
