PROBLEM TO BE SOLVED: To provide a reluctance network to which magnetic detection characteristics can be adapted easily by stabilizing the parameters of a plurality of reluctance elements. SOLUTION: The reluctance network has the plurality of reluctance elements 10 and responds to magnetic fields H<SB>ext</SB>, H<SB>p</SB>. One or at least one reluctance element 10 has at least one reluctance element having a nanoconstriction shape. The nanoconstriction has pads 12, 13 made of at least two magnetic materials. The pads are related to respective magnetizations 16, 17 oriented in opposite directions mutually substantially, and are connected via a nanochannel 11. The nanochannel 11 can arrange a domain wall 15. The domain wall determines the electric resistance of the nanoconstriction as a function of the position of the domain wall 15 formed in a sensor device for the nanochannel 11.
