Abstract: The invention relates to a method and to a device for carrying out a manufacturing process in which all magnet cores to be produced are first continuously crystallized. Depending on whether the required hysteresis loops should be round, flat or rectangular, the magnet cores are either immediately finished, that is enclosed in housings, conditioned to a rectangular hysteresis loop in a direct-axis magnetic field or to a flat hysteresis loop in a magnetic cross-field and then finished.

Abstract: A method for achieving a flat magnetization loop in cores, such as for use in inductive components, which are wound of amorphous ribbon includes the steps of subjecting the wound core to long-term heat treatment of more than 10 hours, and selecting the temperature during the heat treatment so low that less than half of the ribbon cross-section exhibits crystalline precipitations which occur during the heat treatment.

Abstract: A deactivatable security label comprising a low-coercivity strip and a strip having a high coercive field strength can be advantageously manufactured when the alloy of cobalt, nickle and/or iron is employed which exhibits a coercive field strength of between 20 and 50 A/cm given a remanence of more than one Tesla and when this strip is secured to a low-coercivity strip of amorphous material by means of spot welding.

Abstract: A torque sensor has a magnetic foil which is wound and attached to a rotating shaft in strip form at an angle to the shaft axis of rotation, the magnetic strip being mechanically stressed dependent upon the torque acting on the shaft, and generating voltages in two secondary windings surrounding the magnetic strips. The voltages will be different due to different forces acting on the two strips, this being a measure of the torque acting on the shaft. The strips are formed from stamped segments cut obliquely from an amorphous tape which is cast with a profiled cross-machine cross section having regions of varying thickness. Such a tape can be manufactured using a nozzle having a correspondingly shaped orifice opening through which molten amorphous alloy is discharged onto a moving cooling surface.
