Valency of rare earths in RIn3 and RSn3: Ab initio analysis of electric-field gradients

S. Jalali Asadabadi, S. Cottenier, H. Akbarzadeh +2

In RIn3 and RSn3 the rare earth (R) is trivalent, except for Eu and Yb, which are divalent. This was experimentally determined in 1977 by perturbed angular correlation measurements…
