Abstract

It is well known that the magnetic properties of soft ferromagnetic alloys are affected by temperature. In this respect a great deal of work is reported in the literature on the effects of elevated temperatures, but only a few references concerning low-temperature properties are available to design engineers. One of the most com­prehensive papers published on the influence of low temperatures is that of Gniewek and Ploge [1] which deals with Si-Fe and 48 % Ni-Fe strip, both oriented and non-oriented. The increasing use of electromagnetic devices at cryogenic temperatures has created a need for information about other soft magnetic alloys, e.g. the high Ni-Fe permalloys and Co-Fe alloys. This study has investigated the behavior of a number of commercial alloys at low temperatures in an effort to supply some of the desired information.
