  Time differential perturbed angular gamma-gamma-correlation (TDPAC) method on
111Cd nuclei probes inserted in ZrZn1.9 is used to measure the magnetic
hyperfine fields (MHF) at Zr and Zn sites and the electric field gradient (EFG)
Vzz at Zn sites as a function of temperature at various pressures and as a
function of pressure at the temperature 4 K. Our data indicate that the local
magnetic moment of Zr in the magnetically ordered state is substantially larger
than its value obtained from the macroscopic measurements and that there is
also an induced magnetic moment at the Zn site. We conclude that ZrZn2 is not a
simple ferromagnet and discuss a possible type of its magnetic ordering.
