Abstract
Using a model of trivalent Pr ions in PrxY1-xBa Cu32O7 with a crystal-electric-field level structure where the three lowest singlest are separated from the others by a large gap of about 500 K, we show that it is possible to account both for the low-temperature staggered magnetization of the antiferromagnetic ordered Pr ions and for the high-temperature magnetic susceptibility. We discuss the suppression of superconductivity by the magnetic moment of Pr3+ and show the importance of the antiferromagnetic exchange interactions for pair breaking by ions with singlet-level structure. Exchange-interaction parameters are evaluated.
