Very low-temperature magnetic behavior. a Temperature dependence of χT measured at H = 0 and in the region of very low temperatures for different frequencies. Dc data measured under a magnetic field H = 0.1 T are also shown. Experimental data are represented with symbols, and the solid line represents the best-fit for the anisotropic model described in the text. b Magnetization versus field isotherms measured at very low temperatures. Solid curves: measured magnetizations at temperatures given. Symbols: QMC calculated magnetizations using the best-fit parameters given in the text
