The present invention relates to devices and method for melting solid polarised sample while retaining a high level of polarisation. In an embodiment of the present invention a sample is polarised in a sample- retaining cup (9) in a strong magnetic field in a polarising means (3a, 3b, 3c) in a cryostat (2) and then melted inside the cryostat (2) by melting means such as a laser (8) connected by an optical fibre (4) to the interior of the cryostat.

La présente invention concerne des dispositifs et un procédé qui permettent de mélanger un échantillon polarisé solide tout en conservant un haut niveau de polarisation. Dans une forme de réalisation selon la présente invention, un échantillon est polarisé dans un godet (9) à échantillon dans un champ magnétique intense dans un moyen de polarisation (3a, 3b, 3c) prévu dans un cryostat (2) puis l'échantillon est mélangé à l'intérieur du cryostat (2) par un moyen de mélange tel qu'un laser (8) relié par une fibre optique (4) à l'intérieur du cryostat.
