“…Consequently, and to reconcile neutron and µSRstudies, in some studies the muon was assumed to stop at the f site ( 1 4 1 4 1 4 ), which is symmetric between the two magnetic sublattices and for which the dipolar fields cancel (see for example [72]). However, µSR measurements performed on a number of isostructural compounds appear to rule out any occupation of the f site by the muon in the ThCr 2 Si 2 -type structure [74][75][76]. Therefore, it emerges that the observed increased field distribution is somehow connected to the hidden order state and not to a strongly reduced magnetic volume.…”

The behavior of the so-called weak moment antiferromagnetic states, observed in the heavy-fermion superconductors UPt 3 and URu 2 Si 2 , is discussed in view of recent µSR results obtained as function of control parameters like chemical substitution and external pressure. In UPt 3 , 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 magnetic sites deeply affects the fluctuation timescale. In URu 2 Si 2 , a phase separation between the so-called hidden order state, present at ambient pressure, and an antiferromagnetic state, occurring under pressure, is observed. In view of the pressure-temperature phase diagram obtained by µSR, it is deduced that the respective order parameters have different symmetries.
