The oxygen atomicity of the high critical temperature superconductor YBa{sub 2}Cu{sub 3}O{sub x} can be controlled by low temperature anneals in oxygen or argon{sup 1,2,3}. The authors investigated the behaviour of thin films of YBa{sub 2}Cu{sub 3}O{sub x} with reduced oxygen content by carrying out such anneals and examining the structure and electronic properties of the material at intervals. In this paper the shape of the transition for slightly deoxygenated material and the effects of deoxygenation on critical current density in magnetic fields from 0 to 3T are reported and discussed.
