✦ Synopsis

Recent neutron -scattering experiments concerning the magnetic behaviour of Ce (Cur_zNir)2 Gez with varying x are interpreted via the Kondo-lattice picture of Heavy-Fermion systems. The occurence of small ordered moments and small modulation wave-vectors finds a natural explanation in terms of itinerant sntiferromagnetism of heavy quasi-particles.

A study of the full susceptibility of the low -temperature Fermi-liquid allows for a discussion of possible deviations from a Lorentzian line shape.

We present a neutron diffraction study on a polycrystalline sample of the heavy-fermion compound UPd2Ga3. Both the crystallographic and magnetic structure have been determined. Below the antiferromagnetic ordering temperature TN = 13.4 K, uranium moments of 0.50(5)#B orient parallel to the hexagonal

The following issues concerning UPd2A13 are addressed: (i) its anisotropic magnetic phase diagram which can be explained by domain-reorientation effects, (ii) the coexistence between magnetically ordered local 5f moments and Cooper pairs formed by weakly delocalized 5f states and (iii) distinct anom

The superconducting phase diagram of heavy-fermion UPt 3 has been investigated by means of sensitive dilatometry. The thermodynamic analysis indicates that all the phase lines are of second order. Ehrenfest relations reveal that the C phase is the stable phase under uniaxial pressure (p II e).
