Abstract |
Various concentrations of the solid solution Yb2 Pd2 In1−x Sn x ranging from
x = 0 to 1 with the tetragonal Mo2 FeB2 -type structure were prepared and
their physical properties were studied by means of bulk and spectroscopic
measurements as a function of temperature, pressure and magnetic fields.
Results deduced from these studies indicate a slight variation of the valency of
the Yb ions, from ν ≈ 2.9 for both border compounds to ν = 3 at x = 0.6. This
variation gives rise to the appearance of long range magnetic order in a narrow
concentration region around x = 0.6, while both border compounds remain
non-magnetic. The outstanding concentration dependence for the ordered
regime may be indicative of two quantum critical points, a novel feature not yet
observed in Yb compounds. |
