description | Flecher and co-workers in their work on superconducting films niobium, lead and lead-bismuth, have used the reflection of spin-polarized slow neutrons to obtain a direct and absolute measurement of the magnetic penetration depth. In this paper, the authors report the first such measurement of the penetration depth in a sample of yBa//2Cu//3O//7// minus //x. At a temperature of 4. 8 K and in an applied magnetic field of 350 oersteds they obtain a value, which represents an upper limit, of 225 plus or minus 75 Angstroms, which is small compared with penetration depths in conventional superconductors, and with the recently quoted values for YBa//2Cu//3O//7// minus //x and La//1//. //8//5Ba//0//. //1//5CuO//4. |
