The behaviour of the so-called weak-moment antiferromagnetic states, observed in the heavy-fermion superconductors UPt3 and URu2Si2, is discussed in view of recent μSR results obtained as functions of control parameters such as chemical substitution and external pressure. In UPt3, the Pd substitution for Pt reveals the dynamical character of the weak-moment order. On the other hand, μSR measurements performed on samples in which Th substitutes U suggest that crystallographic disorder on the… 
Suppression of hidden order in URu2Si2 under pressure and restoration in magnetic field
We describe here recent inelastic neutron scattering experiments on the heavy fermion compound URu2Si2 realized in order to clarify the nature of the hidden order (HO) phase which occurs below T0 =
Competition of ground states in URu2Si2 and UCoGe
In this thesis two heavy fermion compounds have been studied under pressure. URu2Si2 has a mysterious ground state below T0 = 17.5 K at ambient pressure. The order parameter has not been identified
Heavy-fermion behaviours in URu2Si2
We analyse the magnetic susceptibility χ and the specific heat C of the heavy-fermion material URu2Si2, assuming a variety of the crystal field level schemes. The heavy-fermion behaviours of χ and C
Magnetoelastic coupling in URu2Si2 : Probing multipolar correlations in the hidden order state
Time reversal symmetry and magnetoelastic correlations are probed by means of high-resolution volume dilatometry in URu2Si2 at cryogenic temperatures and magnetic fields more than enough to suppress
Electrical Resistivity and Thermal Expansion Measurements of URu2Si2 under Pressure
We carried out simultaneous measurements of electrical resistivity and thermal expansion of the heavy-fermion compound URu 2 Si 2 under pressure using a single crystal. We observed a phase transition
Muon spin spectroscopy: magnetism, soft matter and the bridge between the two
The use of implanted muons to probe the spin dynamics and electronic excitations in a variety of magnetic and non-magnetic materials is reviewed and is split into three main sections, the first of
