Abstract

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.
