METHOD OF MANUFACTURE OF AMORPHOUS TRANSDUCER ELEMENTS

摘要

The present invention relates to a method for manufacturing amorphous transducer elements with a high magnetomechanical coupling and with various non-planar cross-sectional shapes. According to the invention the amorphous strip or ribbon is arranged in a shaping fixture and is annealed in a two-step process with an intermediate cooling step, the annealing process during the first step being carried out with the strip or ribbon firmly fixed in the fixture but with no influence from any magnetic field, and the annealing process during the second step being carried out at a higher temperature with the strip or ribbon no longer being fixed in the fixture and under the influence of a transverse magnetic field.
