An unusual dinuclear Yb(2) complex isolated using a mixed ligand strategy leads to field-induced SMM behaviour. Low magnetic axiality and a large tunnelling gap lead to significant quantum tunnelling of the magnetisation, which was reduced under an applied static optimum field of 1600 Oe.

The effect of lattice mismatch on the chemical ordering of epitaxial FePt films was studied. The results showed that the lattice constant scd of the FePt films decreased with increasing lattice mismatch « from about 2.23% to 6.33%. Upon further increase of « to about 8.8%, c increased. On the other hand, the variation of the lattice constant sad of the FePt films showed a reversal behavior to t...

A pivotal claim in research on American political behavior is that the typical citizen knows very little about politics. Public opinion surveys provide a considerable body of evidence in support of this position. However, survey protocols with respect to factual questions about politics violate established norms in educational testing in that “don’t know” answers are encouraged rather than disc...
