Multiple peaks in the ac susceptibility of untwinned Y-Ba-Cu-O single crystals: A manifestation of the peak effect
Giapintzakis, John; Neiman, R. L.; Ginsberg, D. M.; Kirk, M. A. (1994)We have measured the ac susceptibility of several high quality twinned and detwinned YBa2Cu3O7- (YBCO) single crystals. We see multiple peaks in the (T) curves, and explain them as a manifestation of the peak effect in ...

Sign reversal of the Hall effect in YBa2(Cu1-x)3O7-δ single crystals
Neiman, R. L.; Giapintzakis, John; Ginsberg, D. M.; Mochel, J. M. (1995)We have measured the in-plane Hall effect and in-plane resistivity of cobalt-doped YBa2Cu3O7-δ (YBCO) single-crystal samples. The concentration of cobalt ranged from 1 to 3%. As the applied field was varied, a sign reversal ...

Transition temperature and irreversibility line of cobalt-doped single-crystal YBa2Cu3O7-: The effect of high-pressure oxygen annealing
Neiman, R. L.; Giapintzakis, John; Ginsberg, D. M. (1994)We have measured the effect of cobalt on the superconducting transition temperature (Tc) and the dc irreversibility line (IRL) of single-crystal YBa2Cu3O7- (YBCO). Tc of a single crystal annealed in flowing oxygen at ...
