Abstract

ZrZn2 is a itinerant magnet with non-Fermi liquid behaviour. The nature of the magnetic order (ferro or antiferro and/or commensurate or incommensurate) is not known, and we perform muon spectroscopy to identify them. Also, critical phenomena above the Neel (or Curie) temperature will be investigated. Reduction of moments and the Neel (or Curie) temperature will be investigated toward the non-magnetic NbZn2 by substitution of (Zr1-xNbx)Zn2
