A. Matsushita et al., PRESSURE EFFECTS ON THE PHYSICAL-PROPERTIES OF (Y1-XPRX)(2)BA4CU7O15-DELTA, Physica. C, Superconductivity, 235, 1994, pp. 1473-1474
We have investigated the magnetic susceptibility at atmospheric pressu
re for the (Y-1-xPr(x))(2)Ba4Cu7O(15-delta) system with x=0.1-0.6 and
that at high pressure for the sample with x=0.6. The effective moment
per Pr ion obtained by the Curie-Weiss fitting is an intermediate valu
e between that expected for Pr3+ and that for Pr4+. It was found that
the magnetic state of Pr ion is scarcely affected by pressure.
