摘要： A thin-film magnetic read head device comprises an end face extending in a first direction, in which a magnetic information carrier is movable with respect to the magnetic head device, and in a second direction, perpendicular to said first direction. The magnetic head device further comprises a multilayer structure (11,13,16,18,19,20) with at least two soft-magnetic layers separated by a magnetic insulation layer and with at least one exchange biasing layer (13), which multilayer structure extends in the second direction and in a third direction, perpendicular to the first and the second direction, and forms at least one flux path (17) in the first and the third direction. The exchange coupling between one of the soft-magnetic layers (16) and the exchange biasing layer (13) is at least partly reduced locally, i.e. interrupted or at least substantially reduced, in at least the second direction, while the exchange biasing layer extends uninterruptedly in the region of said reductions.

摘要： The invention relates to a magnetic field sensor having a magnetoresistance element, comprising a substrate on which two ferromagnetic layers are provided which exhibit a uniaxial in-plane anisotropy and which are separated by a non-magnetic intermediate layer. In accordance with the invention, the anisotropy direction of one ferromagnetic layer extends transversely with respect to the anisotropy direction of the other ferromagnetic layer. By virtue thereof, it is attained that the change of the direction of magnetization in the sensor caused by external magnetic fields is much more uniform and that the corresponding magnetization curve exhibits a smaller hysteresis. When the sensor is used in a magnetic head, an improved signal/noise ratio is obtained.

摘要： A boron-free hard magnetic material on the basis of neodymium, iron and carbon which comprises a hard magnetic, finely crystalline tetragonal phase having a grain size equal to or smaller than 0.2 µm, and which has the Nd₂Fe₁₄C structure. The material can be obtained by spraying a molten alloy onto a rapidly moving chill surface, while forming flakes having a thickness of 30 µm or less. The material thus obtained is subsequently annealed at a temperature between 685 and 730°C, such that the desired structure is formed.
