Abstract
Analysis of the single crystal magnetization curves of Pr2Fe14B measured from 4.2-275 K in fields of up to 18 T, and of the spin reorientation in Yb2Fe14B reveal that there is a reduction of about 50 % in the second-order rare earth crystal field compared to the rest of the series (Nd-Tm). The reduction is attributed to incipient valence instability in these two compounds.
