The magnetocaloric effect (MCE) is the isothermal change of entropy and the adiabatic change of temperature that appears insome materials during the application of a magnetic field. Manganites are a family of compounds with an important MCE.Moreover, the strong coupling between their electronic, magnetic and structural degrees of freedom makes them very flexible tomodify their magnetic properties with different stimulus.With the aim of exploiting the MCE of manganites in microdevices, we studied this effect in La0.88 Sr0.12 MnO3 thin filmsdeposited by pulsed laser deposition (PLD) on silicon substrates. We present here the dependence of the magnetic properties andthe MCE with the thickness and the thermal treatment of the films.
