This thesis attempts to answer the question: what is the superconducting mechanism in ε-iron and CeCu2Si2? There are many reasons to think that it is not a conventional BCS-type mechanism in either system. Pressure enables us to continuously vary the electronic properties of a material, and fluctuations between different electronic configurations at a quantum instability are likely to cause the...
