Breach of faith? Italian-Soviet Cold War trading and Eni’s international oil scandal

The article was submitted on 10.07.2015.By the late-1950s, Soviet oil exports to Western Europe caused widespread concern in a number of Western countries as these feared that Moscow could use oil to weaken their economic interests. At the same time though, other Western countries had no hesitation in developing trade relations with the Soviets, seeing this as a good commercial opportunity. The paramount example of such political nonchalance was Italy’s oil company, ENI. In 1960, ENI signed a barter contract with the Soviets, causing a scandal in the Western oil world: the Italian company’s act was seen as a serious breach of faith by its international allies. As a consequence, ENI’s contract became a serious bone of contention in the country’s bilateral and international relations. This paper analyzes the origins and development of the ENI-Soviet deal, and focuses on the reactions of Italy’s Western allies and the debate it generated at the European Economic Community.В конце 1950-х гг. поставки нефти из СССР в Западную Европу вызвали озабоченность в некоторых европейских странах, которые опасались, что Москва может использовать нефть в целях ослабления их экономических интересов. Однако наряду с этим, другие европейские страны продолжали поддерживать торговые отношения с Советским Союзом, считая их перспективными. Ярким примером такой политической беспечности стала итальянская нефтяная компания ENI (Национальное нефтегазовое учреждение). В 1960 г. она подписала с СССР соглашение о товарообмене, чем вызвала скандал на европейском нефтяном рынке: международные союзники восприняли действия итальянской компании как измену. В результате контракт ENI стал камнем преткновения в двусторонних и многосторонних отношениях Италии с другими странами. В статье рассматриваются предпосылки и этапы развития сотрудничества ENI и СССР, при этом особое внимание уделяется изучению реакции западных союзников Италии и споров, которые это событие вызвало в Европейском экономическом сообществе

Geometrical Description of Quantum Mechanics - Transformations and Dynamics

In this paper we review a proposed geometrical formulation of quantum mechanics. We argue that this geometrization makes available mathematical methods from classical mechanics to the quantum frame work. We apply this formulation to the study of separability and entanglement for states of composite quantum systems.Comment: 22 pages, to be published in Physica Script

Modification of magnetic and transport properties of manganite layers in Au/La_0.67Sr_0.33MnO_3/SrTiO_3 interfaces

The effect of gold capping on magnetic and transport properties of optimally doped manganite thin films is studied. An extraordinary suppression of conductivity and magnetic properties occurs in epitaxial (001) La_0.67Sr_0.33MnO_3 (LSMO) films grown on SrTiO_3 upon deposition of 2 nm of Au: in the case of ultrathin films of LSMO (4 nm thick) the resistivity increases by four orders of magnitude while the Curie temperature decreases by 180 K. Zero-field 55Mn nuclear magnetic resonance reveals a significant reduction of ferromagnetic double-exchange mechanism in manganite films upon the gold capping. We find evidence for the formation of a 1.9-nm thick magnetic "dead-layer" at the Au/LSMO interface, associated with the creation of interfacial non double-exchange insulating phases.Comment: 4 figure

Domain wall displacement in Py square ring for single nanometric magnetic bead detection

A new approach based on the domain wall displacement in confined ferromagnetic nanostructures for attracting and sensing a single nanometric magnetic particles is presented. We modeled and experimentally demonstrated the viability of the approach using an anisotropic magnetoresistance device made by a micron-size square ring of Permalloy designed for application in magnetic storage. This detection concept can be suitable to biomolecular recognition, and in particular to single molecule detection.Comment: 8pages, 3figure
