There is much interest from the physics community in materials with a gapped nonmagnetic ground state, in which quantum critical points can be reached by application of a magnetic field. Here, the authors report magnetization data as a function of temperature, field, and hydrostatic pressure for the gapped quantum magnet CsFeCl3, a quite intriguing system in which the large easy-plane single-ion anisotropy competes with the exchange interactions. They establish the phase boundary, and identify a quantum phase transition at a critical value of the pressure. It is likely that experiments by other techniques will follow this discovery of both magnetic-field and pressure-controlled transitions in this interesting compound.
