✦ Synopsis

It is shown that the experimental data can only be explained in terms of the dominant effect of tl = 5 shell spin polarization. A simple molecular orbital model is shown to lbe capable of giving a parametrized fit to the data.

Very accurate measurements of the pair interaction constants of Gd3+ ions substituted into
