Objective This proposal suggests electron spin resonance studies of gadolinium ions doped in to high temperature superconductors to measure local fields. As shown by the Hungarian group in recent years this method is complementary to NMR studies. Gadolinium substitutes yttrium in the extensively investigated YBa2Cu30y series and serves as an excellent probe of local fields especially at low temperatures where 89Y NMR runs into experimental difficulties. The recent work in high magnetic fields shows that precise measurements of the Gd ESR Knight shift are possible and thus a study on the same samples of 63Cu NMR and Gd3+ ESR is of great interest. The Hungarian team has an experience of two decades in electron spin resonance and in particular in conduction electron spin resonance in metals. High quality perovskite superconductors are synthetized in Budapest with precise X-ray structure determination. ESR studies in low fields at 9 GHz frequency in Budapest together with high field studies at 245 GHz in Grenoble represent a unique possibility to distinguish between various mechanisms giving rise to local fields with electrostatic or magnetic origin. In summary the proposal of the Hungarian team complements well the studies of the Network.
