Low temperature, high frequency permeability of Metglas 2714A and its potential for use as a core material for EMI filters

Abstract

We report the measurement of the relative permeability of Metglas 2714A at 4.2 K temperature and at frequencies up to 1 MHz. We find that at ∼300 kHz, the real part of the relative permeability begins to drop towards unity, while the magnitude of the imaginary part increases. Our data can be used to design transformers and EMI filters for low temperature applications.
