Title:
Quantum {{Phase Transitions}} in the {{Itinerant Ferromagnet}} ${\mathrm{Z}\mathrm{r}\mathrm{Z}\mathrm{n}}_{2}$ 
Abstract:
We report a study of the ferromagnetism of ZrZn2, the most promising material to exhibit ferromagnetic quantum criticality, at low temperatures T as a function of pressure p. We find that the ordered ferromagnetic moment disappears discontinuously at pc=16.5 kbar. Thus a tricritical point separates a line of first order ferromagnetic transitions from second order (continuous) transitions at higher temperature. We also identify two lines of transitions of the magnetization isotherms up to 12 T in...    »
