N2 - In our experiments, fully oxygenated (Formula presented) single crystals were annealed in flowing oxygen at various temperatures and quenched in liquid nitrogen to become oxygen deficient. These single crystals, with transition temperatures ranging from 35 K to 82 K, were then fabricated into mesalike devices along c axis with (Formula presented) plane dimensions down to 2 (Formula presented) We measured dc current-voltage (Formula presented) curves, and observed typical intrinsic Josephson effects such as hysteresis, voltage jumps, etc., in all oxygen deficient samples. However, the oxygen contents and (Formula presented) plane sizes of the samples greatly affected the appearances of the (Formula presented) characteristics, supplying important information on the intrinsic Josephson effects. Microwave responses were also explored for possible high-frequency applications.
