RESUMO

In this work, we measured the oscillatory behavior of the temperature in a single cristal of aluminiumt when termically isolated and subject to a external magnetic field. This effect was used to analyse the, electronic struture of the metal. These measurements was made at 1,2 Kelvin, and the angle of the magnetic field with the axis ( 1,0,0 ) of the cristal was varied of manner to check, through of oscillations periods, our experimental data with the theoretical previsions. The experimental data was anallzated in a computer using a program of Fourier transform. The frequencies thus obtained are in accordance with the theoretical model and the experimental data of other authors using the de Haas - Van Alphen effect.
