Effect of heat treatment on the properties of Metglas foils, and laminated magnetoelectric composites made thereof
Annealing of magnetostrictive Metglas foils, subsequently incorporated into laminated Metglas/Pb(Zr, Ti)O(3) magnetoelectric (ME) composites, is shown to result in improved magnetic properties, as well as ME coefficients. Annealing of the foils at 350 degrees C resulted in partial crystallization, without oxidation or magnetic cluster formation that would reduce the magnetization. Laminate composites made with these annealed Metglas foils had improved ME coefficients. (C) 2010 Elsevier Ltd. All rights reserved.
