Competing interactions and spin-glass-like features in theUCu2Ge2system

Abstract
The experimental results of low field, frequency-dependent complex ac susceptibility including both the linear and nonlinear responses are reported for the UCu2 Ge2 system, where the ferromagnetic long-range order is observed below Tc≊105 K and antiferromagnetic transition occurs at TN≊45 K. The data show various spin-glass-like features in the intermediate FM-AFM temperature regime.
