Administrative Control of the Terms of Insurance Contracts: A Comparative Study

A related article published in this journal, Kimball and Pfennigstorf, Legislative Control of the Terms of Insurance Contracts: A Comparative Study, 39 IND. L.J. 675 (1964), examined legislative and judicial control of the provisions of insurance policies. Ideally, it would have been better to publish all aspects of control of insurance policies in one article, but length as well as complexity necessitated division of the subject matter. The reader who wishes a more complete picture of public control of the terms of insurance contracts should consult the earlier article and other available literature

Anomalous thickness dependence of the Hall effect in ultrathin Pb layers on Si(111)

The magnetoconductive properties of ultrathin Pb films deposited on Si(111) are measured and compared with density-functional electronic band-structure calculations on two-dimensional, free-standing, 1 to 8 monolayers thick Pb(111) slabs. A description with free-standing slabs is possible because it turned out that the Hall coefficient is independent of the substrate and of the crystalline order in the film. We show that the oscillations in sign of the Hall coefficient observed as a function of film thickness can be explained directly from the thickness dependent variations of the electronic bandstructure at the Fermi energy.Comment: 4 pages incl. 3 figures, RevTeX, to appear in Phys.
