Abstract

An invention called Sigmaplug was described, and it is a new development of the Feroplug but using an entirely different physical principle. It was discovered that the sigma phase in Feroplug materials undergoes a ferromagnetic transition at low temperatures and this property can be used to indicate temperature. The new Sigmaplug can extend the operating temperature range of the Feroplug.
