Sentence examples for magnetic layers only from inspiring English sources

He sputter-coated sandwiches of magnetic layers only a few atoms thick, separated by "spacer" layers of non-magnetic metals.

The scanning heads in today's gizmos consist of alternating layers only a few atoms thick of a magnetic metal, like iron, and a nonmagnetic metal, like chromium.

A junction consists of two magnetic layers separated by an insulator.

They found that varying the thickness of the spacer layer actually affected the behaviour of the magnetic layers.

The basic I.B.M. memory unit, which is solid state (it has no moving parts), is made of a lattice of electrodes that have ferro-magnetic sandwiches -- thin magnetic layers -- set at each intersection of the lattice.

Essentially it involves adding a three-atom-thick layer of the element ruthenium, a precious metal similar to platinum, between two magnetic layers.

The microprocessor reads a one or zero by detecting the flow of electrons between the magnetic layers of each sandwich.

The magnetic field of one magnetic layer always remains in one particular direction, the field in the other layer can be switched back and forth.

When a field is switched in the one magnetic layer, resistance drops, representing a "1".

In essence, the spin-valve structure of a GMR head has three very thin layers: a "pinned" layer of magnetic material that is kept in a fixed magnetic orientation; a non-magnetic spacer layer; and a second magnetic layer that changes magnetic orientation as the disk rotates beneath it (see illustration above).GMR exploits a quantum property of electrons called spin.

Such features are generally achieved by the integration of a magnetic layer (e.g. nickel (Ni) or iron (Fe) layer) and an external gold layer, which is obtained by sputtering a gold layer once the microjets are released from the template (covering only one side of the micromotor).
