permalloy

Some of her battle wounds were visible, the permalloy arm and leg.

There was nothing here but junk so old that even the permalloy was beginning to corrode.

Mu-metal was developed by adding copper to Permalloy to improve ductility.

Alpha drummed her fingers on the permalloy table.

Record heads are constructed of laminated permalloy, ferrite, or sendust.

Fresh new permalloy surface skin.

Commercial permalloy alloys typically have relative permeability of around 100,000, compared to several thousand for ordinary steel.

"Here," said a calm, competent voice just before Caleb bent over the permalloy bowl before him and gave up the contents of his last meal.

Permalloy's electrical resistivity can vary as much as 5% depending on the strength and the direction of an applied magnetic field.

Electron lenses are manufactured from iron, iron-cobalt or nickel cobalt alloys, such as permalloy.

This deck incorporates a microphone input for recording and a precision hard permalloy rotating head ...

In this case, the magnetoresistance results from the differences in the coercive forces (for example, it is smaller for permalloy than cobalt).

Sendust is harder than permalloy, and is thus useful in abrasive wear applications such as magnetic recording heads.

This method of cable compensation declined in the 1930s, but by World War 2 many other uses for Permalloy were found in the electronics industry.

In 1914 Gustav Elmen discovered permalloy, a magnetic nickel-iron annealed alloy.

The patent for permalloy was held by Western Electric which prevented Western Union from using it.

The use of permalloy for the magnetic and silver for the non-magnetic layers lowered the saturation field to tens of oersteds.

Comparison of molybdenum permalloy with sendust as energy storage inductors (PDF file)

The first permalloy cable to be put into service was between New York and Horta (Azores) in September 1924.

Each of these layers is made of a pure aluminium layer plus a high permeability ferromagnetic layer, similar in composition to molybdenum Permalloy.

These are made of thin strips of permalloy (NiFe magnetic film) whose electrical resistance varies with a change in magnetic field.

Mu-metal has similar magnetic properties to permalloy but the addition of copper to the alloy increases the ductility and allows the metal to be drawn into wire.

Western Union were in competition with AT&T and the Western Electric Company who were using permalloy.

Racetrack memory uses a spin-coherent electric current to move magnetic domains along a nanoscopic permalloy wire about 200 nm across and 100 nm thick.

The iPhone 3GS has a magnetometer, a magnetoresistive permalloy sensor, the AN-203 produced by Honeywell.
