Abstract
The magnetic susceptibility of YBa 2 Cu 3 O 7- x with various oxygen deficiency (0< x x 0 + A T , with diamagnetic deviation due to the superconducting fluctuation above the T c , without any upturn with decreasing temperature. χ 0 decreases linearly from 5.0×10 -7 to 2.2×10 -7 emu/g, and the linear slope A increases from 0 to 5.6×10 -10 emu/gK with increasing x , although the T c changes from 90 K to 60 K rather discontinuously in this phase. In tetragonal phase samples (0.5< x T -4/3 from the observed static susceptibility is proposed with the aid of EPR results.Keywords
