The specific heat of several poly-and single-crystalline samples of UPt, and UPt,B, 1, has been measured below 1 K. in order to study the substructure in the anomaly below the superconducting transition. A double anomaly has been observed for Czochralski-grown single-crystalline UPt, as well as for

Melt casting processed samples of Bi,Sr,CaCu,O,+d were prepared with oxygen contents ranging from kO.126 to 6=0.22 and characterized by electrical resistance and AC-susceptibility. The r, of this compound is shifted reversibly between 75 and 95 K by annealing in Ar and/or O2 atmospheres for various
In systematic studies of oxygen-deficient Ba2YCu307\_~, we have found that a structural anomaly occurs at the composition where bulk superconductivity disappears. The observed step-like increase in the c lattice parameter, when associated with changes in the atomic positions within the unit cell, in
