Abstract [en]

A large scale Bridgman anvil system has been designed. Steel gaskets permit compression of a methanol-ethanol medium over a volume of 500-250 mm3. Up to 12 wires have been used to contact specimens. The system has so far served up to 7.5 GPa, with anvils made of ASP tool steel. The transition Bi III-V was found to occur at a lower pressure than the recommended average. The electrical resistance of copper was measured up to 6 GPa under hydrostatic conditions.

Original French Abstract: Un système d'enclumes selon Bridgman, mais de grandes dimensions, a été construit. Des joints d'acier inoxydable permettent de contenir un mélange méthanol-éthanol d'un volume de 500-250 mm3. Pour les mesures électriques on utilise jusqu'à 12 fils passant entre le joint et l'enclume. On atteint régulièrement 7,5 GPa avec des enclumes d'acier ASP. La transition Bi III-V se présente à une pression plus basse que la moyenne généralement acceptée. La résistance de cuivre a été mesurée jusqu'à 6 GPa dans un milieu hydrostatique.Available from: 2009-09-07 Created: 2009-09-07 Last updated: 2010-02-03
