Abstract
A ferrite material has been found that is useful for a biasing magnet whose magnetic field stabilizes single wall magnetic domains. The strong temperature dependence of the ferrite's magnetic field makes the ferrite especially useful when used with magnetic materials which require a highly temperature dependent magnetic field to maintain a constant domain or bubble size. The ferrite composition is represented by the formula NiFe.sub.(1+x) Cr.sub.(1-x) O.sub.4, x is in the range between 0.04 and 0.18, and 1 percent to 10 percent, by weight, additional material selected from the group consisting of zirconium oxide, thorium oxide and hafnium oxide.
