Effects of annealing on the physical properties of Bi{sub 2}Sr{sub 2}CaCuO{sub 8+{delta}}
The authors present the measured resistivity, Hall coefficient, and magnetization for three kinds of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} ceramics subjected to various heat treatments. The Hall effect shows that in this system the carriers have hole-like characteristics. The hole density varies according to the heat treatment; the hole density increases and {Tc}. decreases as a result of oxidation. In spite of the atmosphere in which heat treatments were performed, the flux pinning density is increased by quenching. The Hall mobility is independent of the heat treatment of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}}. This result indicates that oxygen atoms enter and leave sites on planes other than the CuO{sub 2} planes in Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}}.
