D. Ravelosona et al., MAGNETIZATION MEASUREMENTS AND IRREVERSIBILITY LINES IN (PRBA2CU3-XGAXO7)(M) (YBA2CU3O7)(N) SUPERLATTICES/, Physica. C, Superconductivity, 235, 1994, pp. 2721-2722
(PrBa2Cu3-xGaxO7)(M)/(YBa2Cu3O7)(N) superlattices have been grown by p
ulsed laser deposition on {100} SrTiO3 substrates with 1 less than or
equal to N less than or equal to 4 and 4 less than or equal to M less
than or equal to 16. Their zero field cooled (Mzfc) and field cooled (
Mfc) magnetisation have been measured by SQUID magnetometry and the ir
reversibility line has been established for each of them.
