Quantum criticality, a process driven by non-thermal parameters such as magnetic field, doping or pressure, when combined with magnetism and electron correlations, can give rise to quantum phase transitions and novel physics. Here, the authors present experimental evidence for itinerant antiferromagnetism in Ti3Cu4, as well as evidence of a magnetic field-induced quantum critical point.
