Anomalous Behavior in Y1−x Pr x Ba2Cu3O7−δ
It is found that the samples of x=0.25 and 0.5 in the series samples of Y1−x Pr x Ba2Cu3O7−δ demonstrate some anomalous behavior. First, the changes of T c value of them are a bit different from their neighbor samples. Second, under a small magnetic field, i.e. 5–100 Oe, a little rise in the T c value with the rise of the field is observed. The anomalous behavior is primitively explained by the local structure changes and the magnetic properties. It is attributed to local structural changes, i.e. the chemical bonds in the Cu–O2 plane.
