| Popis: | We have studied the magnetothermal instabilities in YBa 2 Cu 3 O 7 by using thermal and magnetic measurements. These magnetothermal instabilities consist of flux jumps and temperature jumps, and quasiperiodic oscillations of the temperature and magnetization of the sample. We have interpreted these instabilities with the model primarily introduced by R.G. Mints but taking into account the form of the dissipated power we have found experimentally. The influence of the sweep rate of the applied magnetic field on the appearance of the first flux jump and on the periodicity of the oscillations has been studied. The results are in good agreement with the proposed model. |
