dc.description.abstractRare-earth intermetallic compounds containing ytterbium exhibit a wide range of interesting and unusual physical and magnetic properties. This occurs mainly as a result of their mixed valence states (II/III) or changes from one valence state to the other. Here we present a set of results for the YbMn2SixGe2-x series (8 samples from x = 0 to 2), focusing on the magnetic structure and valence state of these compounds as investigated by neutron powder diffraction (2-530 K). We have found that the valence state of the Yb ion changes from the trivalent state of YbMn2Si2 to a divalent-like behaviour for YbMn2Ge2 with increasing Ge concentration x, with significant changes in the magnetic structure taking place around 1.5<x<1.9 [1]. An overview of the structural and magnetic changes that occur around this critical concentration region will be presented. Emphasis will be placed on current research that focuses on the compound YbMn2Si0.3Ge1.7 in an attempt to characterise the transition.en_US
