Abstract
The magnetic response of two nominal AuGa2 samples has been studied as functions of temperature, applied magnetic field and pressure. These samples display widely different superconducting transition temperatures, critical magnetic field curves and pressure effects. Variations of the initial slope, i.e., (dHc/dT)To, with pressure supports the concept of an electronic transition at about 0.55 GPa. Changes in the magnetic response as a function of pressure suggest that some sort of lattice transformation must also occur at this pressure.

Supercooling is most commonly observed by a hysteresis in the magnetization curve where the expulsion of flux, upon decreasing the magnetic field from above Hc, does not occur until Hsc = Hc(1-x) where x is a few percent of unity.
