Field induced crossover from quantum critical to Fermi liquid regimes a ac susceptibility vs. temperature with applied dc magnetic fields between 0.001 and 8 Tesla. The black arrows denote the approximate values of T* for a fixed dc magnetic field. b The crossover temperature, T*, as a function of magnetic field for a NiCoCr0.8 single crystal as determined from both DC magnetization and ac susceptibility data. The error in T * reflects the uncertainty in determining the temperature of the maximum using either ac or dc susceptibility data. The regions dominated by quantum critical (QC) and Fermi liquid (FL) behavior are noted in the figure. The black line is a power law fit to the data: T* = 5.62 B0.67±0.05 where the error bars are the standard deviation from least squares fitting
