N2 - Studies of zero temperature magnetic phase transitions that exhibit an abundance of nearly critical magnetic fluctuations allow to probe the traditional concepts of the metallic state. For the prototypical heavy fermion compound CeCu6-xAux a breakdown of the Fermi-liquid description may be tuned by either Au-concentration, hydrostatic pressure, uniaxial stress or magnetic field. The d-electron Laves phase ZrZn2, on the other hand, was recently found to display superconductivity in coexistence with itinerant ferromagnetism.
