    1. It's the coupling that creates resistance: Spin electronics in layered magnetic structures (pages 7–16)

      Fast-paced technological advancement is squeezing the data on computer hard disks ever closer together. For some ten years now, continuously shrinking and increasingly sensitive read/write heads are making use of the giant magnetoresistance (GMR) effect discovered in 1988. This term was coined for the effect that electric resistance of a magnetic layer system changes dramatically when the magnetization of the individual layers is reversed from antiparallel to parallel orientation. Very small external magnetic fields suffice to change the orientation and thus give GMR read/write heads their high sensitivity.

    1. Algebraic decomposition of the electromagnetic constitutive tensor. A step towards a pre-metric based gravitation? (pages 17–27)

      E. Matagne

      Article first published online: 24 JAN 2008 | DOI: 10.1002/andp.200710272

      The aim of this paper is to provide an algebraic decomposition of the principal part of the electromagnetic constitutive tensor χμνρσ (a pre-metric structure), in a sum of terms of the form

      where the Z(i) are invariant scalars and gμν(i)unimodular conformal metrics. If the space-time is also equipped with a volume measure, such a decomposition is equivalent to a similar decomposition of the associated area metric, where the gμν(i) are ordinary metrics. It has been recently argued that, if such a particular decomposition should be available, it would then be possible to find a compatible connection and derived tensors.

    2. Geodesic-invariant equations of gravitation (pages 28–51)

      Einstein's equations of gravitation are not invariant under geodesic mappings, i.e. under a certain class of mappings of the Christoffel symbols and the metric tensor which leave the geodesic equations in a given coordinate system invariant. A theory in which geodesic mappings play the role of gauge transformations is considered.
