1. Ey are commerciallyavailableintwotypicalcon gurations:inloose Coilsofat-woundwireandintightlywoundcoilsaround a permalloy rod.

2. Sendust is harder than permalloy, and is thus useful in abrasive wear applications such as magnetic recording heads.

3. The effects of annealing on the electrical resistivity, anisotropic magnetoresistivity and hysteresis loop were studied on sputtered permalloy thin films.
