Magnetization density in paramegnetic UGe3

We have measured the magnetization density in the actinide intermetallic compound UGe3 (cubic AuCu3 structure). The induced moment at 4.2 K with H (applied) = 48 kOe is 0.012 μsub(B)/mol. The most significant result is that a small positive moment of approx. 0.0018 μsub(B) is induced at and near the Ge site, which is unusual because elemental Ge is diamagnetic. The spin density at the Ge site is highly aspherical, showing the nature of the bonding with the uranium wave functions. (orig.)
