Evolution of the ground state of Yb ion in YbCu5-xSnx
Source abstract
Abstract
Structural and magnetic studies have been carried out for the cubic YbCu5-xSnx system of the MgCu4Sn-type, which exists in the solubility range 0.2 ≤ x ≤ 0.7. The magnetic properties of this system were compared with those of the analogous system YbCu5-xInx (0.1 ≤ x ≤ 1.0). These two systems appear to share the same scenario of evolution from a localized trivalent state of the Yb atom for low values of x(x = 0.2) to valence transition state in a wide temperature range (T ∼ 40–80 K) for intermediate values of x(x = 0.6, 0.7). Specific heat measurements performed for one of these compositions, YbCu4.4Sn0.6, show an increase at low temperatures T < 7 K most probably due to the presence of a high density of magnetic excitations.
