M. Zazo et al., EXPERIMENTAL-STUDY ON MAGNETIC-RELAXATION IN YBA2CU3O7 BY MEANS OF A SIMPLE INDUCTIVE TECHNIQUE, Applied physics. A, Solids and surfaces, 57(3), 1993, pp. 239-242
The time dependence of the field-cooled susceptibility in polycrystall
ine samples of YBa2Cu3O7 has been studied in the temperature range 77-
95 K. Field-cooled and zero-field-cooled susceptibility measurements a
nd its variation with the ac magnetic field are also reported. Measure
ments have been carried out by means of an inductive technique. Our fu
lly automatic system allows us to measure the first data points of fie
ld-cooled susceptibility versus time from the beginning of the magneti
c relaxation just after removing the field.
