We discovered that in thin amorphous tapes with an extremely low magnetostriction, annealed under mechanical pension, it is possible to reach enormously high level of non-diagonal magnetoimpedance with nearly linear dependence on the applied magnetic field [L. Kraus: J. Magn. Magn. Mater. 320 (2008) e746, doi:10.1016/j.jmmm.2008.04.043]. This phenomenon was successfully utilized for design of a simple, extremely sensitive, and cheap magnetic field sensor [M. Malátek, L. Kraus: ready for publication in Sensors&Actuators A].
