Abstract
A magnetic glassy metal alloy sheet is annealed at elevated temperature in a first magnetic field oriented in a direction substantially normal to the plane of the sheet. A second anneal may be performed in a weaker magnetic field in a direction substantially normal to the first field to minimize AC hysteresis losses. The annealed magnetic glassy metal alloy sheet has improved soft magnetic properties such as low hysteresis losses and may be used for transformer cores and the like.
