Summary on Grant Application Form |
|
High resolution measurements of the magnetic penetration depth have proven to be an invaluable tool for probing the fundamental nature of the superconductivity. In particular the discovery of a strong linear term in the temperature dependence of the penetration depth of the high Tc superconductors (HTSC) has been a key piece of evidence in favour of d-wave superconductivity. There is however non conclusive evidence for the predicted signature of d-wave superconductivity in the FIELD dependence of the penetration depth. The proposed research aims to study both the field and temperature dependence of the penetration depth in a number of HTSC and other possible non-conventional superconductors (such as the organic superconductors, the layer perovskite materials (Sr2Ru04), and heavy fermion materials). The aim of these experiments is to probe the fundamental nature of the superconductivity in these compounds (in particular the symmetry of the order parameter). The HTSC experiments will concentrate on ultra high purity crystals of YBCO (grown in BZO) which have recently become available, as well as the Hg and Tl based materials. Experiments will be conducted well below 1K using a dilution refrigerator, in order to extend greatly the regime of temperature which has been probed to date.
