The process for the production of at least one silicon-based nanoelement (), in particular a nanowire, comprises the following stages: providing a substrate comprising, at the surface, a first layer () comprising electrically doped silicon; forming, on the first layer (), a second layer () based on silicon oxide with carbon atoms () dispersed in the said second layer (); and exposing the first and second layers () to an oxidizing atmosphere, so as to oxidize at least a first section () of the first layer () at the interface of the said first layer () with the second layer () and to form the said at least one nanoelement () at the said first section ().

The invention relates to a method for making an actuation system for an optical component comprising:

Optical components and production thereof

A magnetoresistive component and transducer for use therewith. The magnetoresistive component has a multilayer-type magnetoresistive strip bent in accordance with a repeated geometrical pattern (7a,7b). The pattern has at least one series of substantially parallel sections (7a,7b) for reducing the demagnetizing fields. The magnetoresistive strip (2) is formed from a stack (13) of magnetic metallic material layers (14) separated by non-magnetic metallic material layers (15). The magnetoresistive component is applicable to a transducer for reading information recorded in magnetic form or for detecting weak magnetic fields.

Process for producing a magnetic head with an appropriately oriented easy axis of magnetization and head obtained by this process. According to the invention, a large magnetic pattern (52) is formed around a spacer and then said pattern is etched in order to give it the desired shape. In the narrow horizontal branch, the easy axis of magnetization is oriented parallel to the air gap. Application to magnetic recording.
