Abstract:

The scope of this project is twofold. The first step is to implement an original method to measure the temperature dependence of the London penetration depth, λ, under hydrostatic pressure and external magnetic fields using a proximity detector oscillator (PDO). The penetration depth study is a particularly useful toll to investigate unconventional superconductivity in particular the symmetry of the order parameter and so far it only has been done at ambient pressure. Therefore, in case of success, our method will be a premiere at both national and international level. Studies using this method can be readily applied to a large variety of superconductors or even use to measure contactless impedances under pressure for a large number of compounds. It will also call for revisiting superconductors with interesting properties under pressure as for example heavy fermion systems. Therefore the data outcome which such an experimental setup is expected to be significant. The second step of this project is to use this method to study selected superconductors from the pnictide family which is at the moment of great scientific interest.

Abstract:

FeAs based compounds are a new class of superconductors that have extremely interesting properties that may even allow them to become technological materials. When taken in the context of the high-Tc oxides, they present the hope that perhaps some clue to exotic superconductivity may be more clearly manifest in the FeAs system and will reveal details of pairing mechanism and help the development of the theory for the copper oxide systems. Also Fe2As2 further emphasize that superconductivity is a rather ubiquitous, low temperature ground state for metals and even semimetals. Despite the huge experimental effort, the detailed properties of these systems are only beginning to be revealed. Is the main objective of the present project to shade more light into the Cooper pairing mechanism and into the symmetry of the order parameter by studies under hydrostatic pressure and as function of systematic doping. Will be further rewarding if we will, as a side effort, manage to enhance superconducting transition temperature.
