We report on the temperature variation of the interatomic distances in isostructural U 2 Ni 2 In and U 2 Pd 2 Sn, both of which order antiferromagnetically at low temperatures. Both compounds exhibit complex non-collinear arrangements of the magnetic

Single crystals of the heavy-electron compound have been grown by a modified mineralization technique. The x-ray structure refinement shows that single crystals form in the structure, instead of the structure reported for polycrystalline material. Th

PAC measurements on show that the U moments are oriented mainly along [001] in an AFII type ordering. A small scale deviation from this ordering must be present, for which two possibilities are proposed. There are several indications that on top of t
