Dear All, I am curious to know about some materials listed below- Mumetals, Permalloy, Supermalloy, Permendur, Perminvar and Sendust. I am interested to study there magnetic properties like permeability, hysteresis, temp. dependance of magnetism etc, if possible coefficient of thermal expansion and low temperature properties etc. I searched a lot on internet but wont found much info about same. Please provide the sources (weblinks, books, papers etc). It will be great help...thanks in advance. Regards S.
