Polarised neutron diffraction measurements on polycrystalline CeFe 2 and LuFe 2 , the end members of the rare-earth (R)-based RFe 2 Laves phase compounds show, in both compounds, a clearly measurable flipping ratio, of less than unity, on the (2 2 0)

We have made inelastic neutron scattering measurements on the doped Kondo insulators Ce(Rh0.8Pd0.2)Sb and (Ce0.7Th0.3)RhSb. Previous bulk property measurements showed non-Fermi liquid (NFL) behaviour for both compositions. In our inelastic neutron sc

We have made inelastic neutron scattering studies of Ce(Rh0.8Pd0.2)Sb, which is located at the crossover from non-magnetic to magnetically ordered states (i.e. close to a quantum critical point). In the imaginary part of the dynamic susceptibility, w

Atomic short-range order is commonly observed in _CuMn alloys via a diffuse (1 ½ 0) peak in neutron diffraction patterns. There has been speculation for many years on the existence and nature of any corresponding long-range order. A sample of Cu80Mn

The crystalline electric field (CEF) of RNiSb ( R = Ce , Pr, Nd, Tb, Dy, Ho, Er and ( Er 0.1 Y 0.9 ) ) has been investigated by inelastic neutron scattering measurements and compared with the theoretical CEF-simulations. The determined CEF level sche

We have studied the magnetic excitation spectrum of CeNiSn at low energies both on a polycrystalline sample using time-of-flight technique and on a single crystal with a triple axis spectrometer. The energy gap in the excitation spectrum is clearly o

We report measurements of the low-temperature ground-state (2F52) paramagnetic spectral response of the compounds CeRh2 and Ce(Rh0.73Pt0.27)2. Both compounds show broad lorentzian-like, single-ion spectral response with characteristic energies of ∼

Ternary compounds of CeM 2 X 2 type (M Cu, Ni; X Sn, Sb) were investigated by inelastic neutron scattering using the time-of-flight spectrometer IN5 at Institute Laue-Langevin. Two incident neutron energies of 2.7 and 6.6 meV were used. Inela

We have performed polarized neutron diffraction measurements on the intermediate valence compound CePd3 using the D3 spectrometer at the ILL. The results show that at low temperatures, 1.7 K , as well as at 100 K , the field-induced magnetic amplitud

We have studied the evolution of the magnetic spectral response over a wide energy range across the γ→α transition in YbInCu 4 . Above T v , the magnetic response is that of a heavy fermion compound showing a central quasi-elastic distribution of
