The behavior of electrical resistance in magnetic fields is described for high quality CVD superconducting oxide films exhibiting very high critical currents at liquid nitrogen temperature, even in high magnetic fields up to 27 T. Results are discussed on the basis of the recent idea of flux creep. The most promising material for application seems to be the Y(RE)-Ba-Cu oxide system.
