Abstract: A magnetoresistive sensor element has a first magnetic layer structure, a second magnetic layer structure, and a barrier layer. The resistance R1 of the first magnetic layer structure, the resistance R2 of the second magnetic layer structure and resistance-area product RA define a characteristic length ? of the magnetoresistive sensor element by a functional relation. The contact spacing X0 has an m-fold value of the characteristic length ? with 0.1<m<20, the first contact terminal a first edge spacing X1 from the edge of the first magnetic layer structure with an n-fold value of the characteristic length ? with 0.5<n, the second contact terminal a second edge spacing X2 from the edge of the first magnetic layer structure with a p-fold value of the characteristic length ? with 0.5<p, the resistance R1 a q-fold value of the resistance R2 with q>1.

Abstract: A method for transferring data representing a network topology from a first software environment to a second software environment is provided. The data are reformatted for this purpose, since it is assumed that the different software environments support different file formats, as is the case, for example, with customary network design programs or network simulation programs. Furthermore, the data are reorganized before or after the reformatting in such a way that a different mapping of the network topology results. Consequently, the method allows an automatic transfer of network topology data from one software environment into another, even though the two software environments use different data formats and different topology representations.
