A liquid magnet.... The melt of an alloy(Co80-Pd20) which is ferromagnetic in the solid state at room temperature was undercooled below its melting point. The freely suspended droplet(diameter approx. 7 mm)-processed in the coil of an electromagnetic levitation facility-was attracted by a permanent magnet when the temperature approached the Curie temperature(lower picture). The attractive force depends on the temperature in a way characteristic for ferromagnetic materials. This appears to be the first demonstration for the possible existence of long-range magnetic order even in a liquid.  1, record 2, English, - liquid%20magnet

Users of permanent magnets know of the very high magnetic coercivity exhibited by certain rare earth-iron alloys, most commonly neodymium-iron-boron... but also including such other rare earth elements as dysprosium for higher anisotropy... Very similar alloys have been developed which excel in related magnetic properties. Take for example, the alloy with terbium and dysprosium commonly known as Terfenol-D... which exhibits a very high magnetostriction; this alloy is said to have "Giant" Magnetostriction.  2, record 4, English, - Terfenol%2DD

... a miniature actuator ... utilizes a Terfenol-D rod; only the end of the rod is visible, attached to a metal dome for actuation. The length of the rod changes as current is applied to the coil surrounding it. The housing acts as part of the magnetic circuit, which also includes a conventional permanent magnet for biasing (not visible). Thus, actuation is provided only by the changing length of the rod, although some mechanical amplification (e.g.: using a lever arm) may be advantageous.  2, record 4, English, - Terfenol%2DD

Les magnétorestrictifs sont utilisés dans les sonars pour générer des ondes acoustiques en faisant osciller un barreau sous l'action d'un champ magnétique alternatif. On a construit aussi des moteurs linéaires capables de déplacer de très fortes charges à de très faibles vitesses, par exemple pour les positionner avec précision. A l'inverse, les magnétorestrictifs sont utilisés dans des capteurs : ils transforment alors un déplacement en un signal électrique. La robotique, l'instrumentation scientifique et médicale, ou bientôt, les «matériaux intelligents» font partie des domaines d'application des magnétorestrictifs.  1, record 6, French, - magn%C3%A9torestrictif

The hard-disk drive is a wonder of modern technology, consisting of a stack of disk platters, each one an aluminum alloy or glass substrate coated with a magnetic material and protective layers. Read-write heads, typically located on both sides of each platter, record and retrieve data from circumferential tracks on the magnetic medium. Servomechanical actuator arms position the heads precisely above the tracks, and a hydrodynamic air bearing is used to "fly" the heads above the surface at heights measured in fractions of microinches.  1, record 10, English, - servomechanical%20actuator%20arm
