[...] la magnétocardiographie, mesure du champ magnétique émis par le cœur à chaque pulsation, pourrait faire appel à de nouveaux magnétomètres ultrasensibles composés d’une fibre optique sur laquelle est déposée une fine couche de verre métallique 2605 SC Metglas. La moindre variation de champ magnétique déforme cette couche de verre métallique, ce qui entraîne une modification du chemin optique dans la fibre, aisément mesurable au moyen d’un petit interféromètre, le tout fonctionnant à température ambiante. Ainsi, on ferait avec ce type d’appareil l'économie de l'hélium liquide, actuellement indispensable avec les coûteux magnétomètres à boucle supraconductrice(SQUID). Et pour le patient, quel confort : plus besoin d’électrodes comme en électrocardiographie! 3, record 1, French, - magn%C3%A9tocardiographie

Notre groupe à l’université technique d’Helsinki est installé dans une pièce blindée magnétiquement par du mu-métal. Le mu-métal supprime les champs magnétiques extérieurs constants ou lentement variables. Mais il y a aussi des champs extérieurs qui changent avec des fréquences plus élevées, de quelques hertz ou kilohertz, et ces fréquences sont celles qui nous intéressent dans les champs magnétiques cérébraux. Pour nous isoler de ces champs extérieurs, nous avons ajouté trois épaisseurs d’aluminium. Comme dans les premières expériences, nous mesurons le champ magnétique près de la tête du sujet avec des SQUID, mais depuis 1970, ceux-ci ont connu bien des améliorations.

Superfluid Helium What Is It? As the temperature of helium gas is lowered to approximately 5.2°K, a phase transition to ordinary liquid helium (He I) takes place. The latter is unremarkable and its behavior is identical to any other liquid. As temperature is lowered further (at moderate pressures) helium does not solidify. Rather, it undergoes a phase change to a second liquid phase He II at temperature of about 2.17°K. ... the He II phase persists all the way to absolute zero. ... The He II phase is referred to as superfluid helium because of its remarkable properties, including the ability to flow through microscopic passages [holes as small as 10-7 centimeters in diameter] with no apparent friction; the quantization of vortices; and the ability to support four wave modes: first sound which is analogous to sound in ordinary gases and liquids, second sound which carries temperature and entropy perturbations with virtually no pressure variations, third sound which are waves on thin films, and fourth sound which are acoustic-like waves in the "superfluid" component of He II. 5, record 15, English, - helium%20II
