Abstract
The time dependence of the field-cooled susceptibility in polycrystalline samples of YBa2Cu3O7 has been studied in the temperature range 77–95 K. Field-cooled and zero-field-cooled susceptibility measurements and its variation with the ac magnetic field are also reported. Measurements have been carried out by means of an inductive technique. Our fully automatic system allows us to measure the first data points of field-cooled susceptibility versus time from the beginning of the magnetic relaxation just after removing the field.
