Title:
Pressure-Induced Magnetic Quantum Phase Transition in {{CeSi1}}.81 
Abstract:
We report the DC magnetisation of the easy-plane ferrimagnet CeSi1.81 for magnetic field in the range $\pm$0.5T as a function of temperature T down to 2.3K and hydrostatic pressure p up to 14.4kbar. We observe that the magnetic moment for the crystallographic a-axis vanishes continuously at pc$\approx$13$\pm$0.2kbar. The variation of the ordered moment as function of pressure at low T is qualitatively similar to its variation as function of temperature at p=0, hinting at the possible existence o...    »
