Title

CeCo1-xFexGe3 - inelastic excitations for x = 1 and near the Quantum Critical Point (x~0.6)

Abstract

We have recently studied a transition between the CeCoGe3 antiferromagnetic compound (TN1 = 21 K, TN2 = 12 K, and TN3 = 8 K) and the nonmagnetic heavy fermion CeFeGe3. This series of compounds CeCo1-xFexGe3 is in a focus of our interest as for x~0.6 it exhibits a Quantum Critical Point. We have found that the crystal electric field (CEF) plays a crucial role in the properties of these alloys. The objective of the planned inelastic neutron scattering in combination with other methods (specific heat, magnetic susceptibility, thermopower) is to determine unambiguously the scheme of the CEF levels.
