saturation flux density of nife alloy

Saturation Flux Density - an overview ScienceDirect

NiFe film is widely used as a magnetic material for microinductor and microtransformer since it has high relative permeability (~ 800) and high saturation flux density ( B s) (~ 1T). While, the typical disadvantage of low electrical resistance has limitations for their high frequency applications. It has been found that Finemet alloy showed superior soft magnetic properties beyong the conventional soft magnetic

Magnetic properties of electroless-deposited NiFeB

1995-11-1  The electroless-deposited NiFeB film with 27at% Fe content had the lowest coercivity, Hc, as low as 0.5 Oe with a saturation magnetic flux density, Bs, of 1.0 T. The saturation magnetostriction, λs, and the uniaxial magnetic anisotropy, Hk, were 5.0×10-6 and 10 Oe, respectively, which were larger than those of the conventional, electrodeposited permalloy film.
