Abstract
We review experiments on Li(Ho,Tb)pY1-pF4 which test ideas about quantum critical phenomena in the clean (ferromagnetic) and disordered (spin glass) limits. The outstanding problem of the ‘anti-glass’ discovered for p=0.045 is also described. Finally, we point out the ubiquity of quantum critical points in condensed matter physics.
