The measurement of the de Hass-van Alphen effect in ZrZn2 under hydrostatic pressure where curi temperature vanishes, was described. The Fermi surface (FS) properties of ZrZn2 at ambient pressure was investegated and dHvA measurement were found consistent with energy band calculations. The low pressure study shows that the standard model for metallic magnetism, the Stoner-Wohlfarth (SW) model cannot account for the magnetic field dependence of the dHvA splitting. The new phase diagram for ZrZn2 predicts the existence of a first order quantum critical point at a small negative pressure.
