High temperature magnetic studies of nanocrystalline Fe69.5(CuCrV)9.5Si13B8

Analysis of the Nanocrystalline Phase Formation Process in Amorphous Fe-X-Si-B Alloys

“…The observed effect of an increase in magnetic permeability, is the result, among other things, of the influence of the crystalline compound on the effective anisotropy constant K and the effective coefficient of magnetostriction. From the random anisotropy model the effective anisotropy constant may be written [2,4] as where K1 is the local anisotropy constant of crystallites of dimension D, and N is the number of crystallites in the volume L3ex, where…”

“…Introduction During recent years materials of nanocrystalline structure have attracted considerable interest [1][2][3]. Advantageous magnetic and electric characteristics for these alloys may be obtained by choosing a suitable chemical composition.…”

Magnetic properties of amorphous and nanocrystalline alloys based on iron

“…The first widely studied alloy from this group was -Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 -FINEMET [1], which at present is already used in practice. Later examinations have shown that other nanocrystalline alloys like FeCu 1 Zr 7 B 6 [2] and Fe 69.5 (CuCrV) 9.5 Si 13 B 8 [3] exhibit also very interesting soft magnetic properties. Nowadays in literature different families of nanocrystalline alloys are discussed e.g.-NANOPERM (Fe-Cu-M-B) or HITPERM (Fe, Co-Cu-M-B) [4].…”
