Abstract
YBa2Cu3O7-x/ferrimagnetic heterostructures were prepared by screen pri nting onto a Y3Fe5O12 garnet film epitaxially grown on a Gd3Ga5O12 Sub strate, followed by oxygen annealing. The superconductor powder was pr epared by the nitrate route and doped with silver. The optimum heat-tr eatment schedule involves short-term annealing at 930 degrees C, follo wed by cooling with halts at 700 and 500 degrees C. The best heterostr uctures show T-c(R=0) = 86 K.
