## Description

- description: Soft magnets are important components in high-frequency power electronic
    devices, significantly contributing to efficient energy conversion. They are commonly
    utilized in transformers, inductors, and magnetic cores within high-frequency
    power converters. However, cutting-edge power electronics technologies demand
    soft magnets with minimal core loss at high frequencies. This study demonstrates
    that high-frequency core losses in Fe-based soft magnetic ribbons can be reduced
    through nanostructure engineering. We present the optimal microstructure designed
    to minimize core losses in the 10-20 kHz frequency range.
