Magnetic behavior of Ce(Cu1-xAgx)6
- 1. Department of Physics, University of Florida, Gainesville, Florida 32611 (USA)
Description
We have investigated doped CeCu6 via x-ray diffraction, dc and ac susceptibility, and specific heat in zero and applied magnetic field with a primary focus on the magnetic behavior caused by Ag doping. We present evidence from bulk specific heat and metallography data that the limit of Ag solubility in Ce(Cu1-xAgx)6 is x∼0.1. Data below the magnetic ordering temperature may be fit to an exponential temperature dependence, implying a weak-coupled energy gap of Δ=0.58 K, contradicting an earlier report that C behaves linearly with temperature with a γ over 3 J/mol K2 in the ordered state. Comparisons to magnetically ordered, doped UPt3 are made
