Antiferromagnetic criticality at a heavy-fermion quantum phase transition
/ Authors
/ Abstract
The identification of the magnetic-fluctuation mode at a quantum phase transition of the archetypical heavy-fermion compound Ce1−xLaxRu2Si2 indicates that quantum criticality in this system is governed by collective antiferromagnetic behaviour, rather than by local magnetic moments as has been suggested.
