Compounds such as YbRh2Si2 with its (2nd order) quantum critical point and Sr3Ru2O7, which is close to a (1st order) quantum critical end point, have become models of quantum critical behavior.
After introducing YbAgGe I will present and discuss thermal expansion and magnetostriction data and argue that YbAgGe exhibits multiple kinds of quantum criticality.
