At ambient pressure, the 1st order metamagnetic transition at 0.7T from the paramagnetic ground state to the field-induced ferromagnetic state changes to a crossover at finite temperature 11K. With increasing pressure, linearly increases, while decreases and is suppressed at the quantum critical endpoint (QCEP). We compare our results on UCoAl with those of UGe and SrRuO.
