ABSTRACT
We report on a change in the valency of the Eu ions in cubic EuPd3 upon Ce substitution. The resultant compound Ce0.5Eu0.5Pd3 exhibits a mixed-valent state of Eu, where the valency differs from +3 observed in the case of EuPd3. This change in the valency also manifests in significant modifications of magnetic properties of Ce0.5Eu0.5Pd3 in comparison to that of EuPd3 and CePd3. In contrast to the usually observed expansion of the lattice accompanied with such valence transitions, our results suggest that the lattice volume in the present case remains essentially constant with respect to EuPd3.

    We performed energy-band calculations for the L10 pseudobinary bulk alloy FePt1-xMx(M =Ir,Au) by using the linear muffin-tin orbital method with atomic sphere approximations. The exchange-correlation potential was treated within the generalized gradient approximation. The total energies for the...
