Temperature Dependence of Magnetic Losses
The rapidly increasing use of electric motors, transformers, and other electrical equipment operating at cryogenic temperatures has created an urgent need for engineering data on the low-temperature magnetic losses of ferromagnetic materials. Unfortunately, such data have been very scarce. Therefore, a research program in this field was begun under the sponsorship of the Advanced Research Projects Agency. The research is continuing; only the results on the first group of materials are presented at this time.
