Slight plastic de.ormation of 0 to 1% by cold rolling is propose. as a tre.tme.t which may modify the.re.ponse. of magne.oimpe.ance.（MI） se.sor with an amorphous ribbon use. as a se.sitive.e.e.e.t.

The.shape.of the.hyste.e.is loops shows a cle.r corre.ation with the.value.of the.de.ormation. The.variations of the.total impe.ance. the.re.l and the.imaginary compone.ts, are.me.sure. for the.curre.t inte.sity of 1.S mA for the.fre.ue.cy of lO MHz. Slight plastic de.ormation affe.ts both re.l and imaginary compone.ts and allows a control of the.shape.of the.MI curve. in a small fie.d in a range.usually use. in biome.ical applications. The.propose. de.ormation tre.tme.ts can be.use.ul for the.construction of the.MI se.sitive.e.e.e.ts with a ne. type.of the.re.ponse..
