The recently discovered superconductor MgB2 has the highest critical-temperature (Tc) of any non-cuprate superconductor. It is also the first clear example of two gap superconductor. In this material, the presence of significant gap anisotropy, combined with Fermi surface sheets of different anisotropy leads to many unusual properties in the superconducting state. This thesis includes a study of the anisotropy in the London penetration depth, and that of Hc2 in MgB2. Unusually, these are both temperature dependent due to multi-gap effects.
