Abstract

The volume dependence of the magnetic properties of U(In_1-xSn_x)₃, with x=0.2 and 0.4, has been studied using ¹¹⁹Sn nuclear forward scattering of synchrotron radiation and Mössbauer spectroscopy at high pressures up to 25 GPa. The results show that in U(In_0.8Sn_0.2)₃ the 5f magnetic moment is almost localized. Pressure induces an increase of the Néel temperature, while the transferred magnetic hyperfine field shows no change. Conversely, in U(In_0.6Sn_0.4)₃ the transferred field decreases monotonically with increasing pressure and the Néel temperature goes through a maximum, showing a clear delocalization of the 5f electrons. This is discussed in terms of 5f-ligand hybridization and appears to lead to the formation of a high-pressure state characterized by strong dynamical spin correlations.
