Coercivity, C.
Let us note that the
coercivity and continuity conditions are sufficient but not necessary as is shown in the forthcoming examples.

coercivity in nanocomposite permanent materials," Journal of Applied Physics, vol.
The boundedness of {[u.sup.n]} is a consequence of the decrease of {[THETA]([u.sup.n])}, the weak
coercivity of [THETA], i.e., [THETA](u) [right arrow] [infinity] as [parallel]u[parallel] [right arrow] [infinity], and Condition 2 of Assumption 2.
Coercivity ([H.sub.C]) is the reverse field required to reduce the magnetization to zero from saturation magnetization.
Banks generally use lo-co tape for ATM cards, although many are now moving to medium
coercivity (mid-co) for better data retention.
Since
coercivity is measured and rated as a bulk property of magnetic media, it is an average property with contributions from individual particles of the media.
which is nonnegative because of the
coercivity of [O.sup.n].
Neodymium plays an important role in maintaining high
coercivity (the ability to maintain magnetization) and heat resistance.
