EU-MIGRATION IN THE CONTEXT OF LIBERALIZING AGRICULTURAL MARKETS

The paper discusses the relevance of migration in the course of the forthcoming eastern enlargement of the EU focusing on the liberalization of the agricultural markets. The technical basis of this research is represented by the general equilibrium model GTAP comprising a survey of existing applications and own calculations including migration.Labor and Human Capital,

Itinerant Ferromagnetism in the electronic localization limit

We present Hall effect, $R_{xy}(H)$, and magnetoresistance, $R_{xx}(H)$, measurements of ultrathin films of Ni, Co and Fe with thicknesses varying between 0.2-8 nm and resistances between 1 M$\Omega$ - 100 $\Omega.$ Both measurements show that films having resistance above a critical value, $R_{C}$, (thickness below a critical value, $d_{C}$) show no signs for ferromagnetism. Ferromagnetism appears only for films with $R<R_{C}$, where $R_{C}$ is material dependent. We raise the possibility that the reason for the absence of spontaneous magnetization is suppression of itinerant ferromagnetism by electronic disorder in the strong localization regime.Comment: 4 pages, 4 figure
