Critical properties at the field-induced Bose-Einstein condensation on NiCl2-4SC(NH2)2
Abstract
We report new magnetization measurements on the spin-gap compound NiCl{sub 2}-4SC(NH{sub 2}){sub 2} at the low-field boundary of the magnetic field induced ordering. The critical density of the magnetization is analyzed in terms of a Bose-Einstein condensation (BEC) of bosonic quasiparticles. The analysis of the magnetization at the transition leads to the conclusion for the preservation of the U(1) symmetry, as required for BEC. The experimental data are well described by quantum Monte Carlo simulations.
