1. A magnetoresistive network responsive to a magnetic field of the type comprising a plurality of magnetoresistive elements, wherein one or more said plurality of magnetoresistive elements comprise at least one magnetoresistive element in the form of nanoconstriction, said nanoconstriction comprising at least two pads made of magnetic material, associated to which are respective magnetizations oriented in directions substantially opposite to one another and connected through a nanochannel, said nanochannel being able to set up a domain wall that determines an electrical resistance of said nanoconstriction as a function of the position, with respect to said nanochannel, of said domain wall formed in a sensor device.
