    On the evolution of the ground state in the system U x La 1 - x S: Polarized neutron diffraction and X-ray magnetic circular dichroism study

    In the UxLa1-xS system there is an abrupt loss of the long-range ferromagnetic ordering found in pure US at a critical concentration x c ∼ 0.57, which is far above the percolat...

    Magnetic structures inRNiAl compounds (R=Pr, Nd, Tb, Dy, Ho and Er)

    Magnetic ordering inRNiAl compounds (R=Pr, Nd, Tb, Dy, Ho and Er) can be described by a propagation vectork=(1/2,0,q). In most cases q=0.5 but incommensurate propagating is observed in PrNiAl (q=0.41) and NdNiAl ...
