A quantum multi-critical point in CeCu 6- x Au x

Robinson, R A; Goossens, Darren; Torikachvili, M S; Kakurai, K; Okumura, H


CeCu6-xAux is a well-known heavy-fermion system in which the ground state is antiferromagnetically ordered for x>0.1 and temperatures below 1 K. Non-Fermi liquid behaviour occurs around this critical concentration. The parent compound, CeCu6, exhibits a structural phase transition near 230 K, where it changes from the Pnma orthorhombic room-temperature structure to the P21/c monoclinic structure. The monoclinicity increases as temperature falls, with β reaching 91.44° at 10 K. In the work...[Show more]
