|Title:||Tailoring Coercivity In An Array Of Glass-coated Microwires|
De Menezes F.S.
|Abstract:||The influence of long-range dipole-dipole interaction on the coercivity of an array of glass-coated CuNiCo microwires is investigated by means of magnetic hysteresis measurements and Monte Carlo simulations. The microwires exhibit a granular structure consisting of Co grains in a Cu-rich matrix. Hysteresis loops for an array of N microwires (1 < N < 100), performed at room temperature, show that HC changes abruptly from 20 to 700 Oe for N around 10. This property allows us to tune HC choosing N, and promises to be useful for practical applications. © 2001 Elsevier Science B.V. All rights reserved.|
