The present invention relates to a compound exhibiting Giant Magneto-Impedance (GMI) properties. The general chemical formula of the compound is (FeCo)CrSiB, characterized in that &#x3b1;&#x3c;&#x3b2; and &#x3b1;&#x3c;&#x3b3;, wherein &#x3b1; is preferably in the range of 2 to 4% by weight, &#x3b2; is preferably in the range of 11.5% to 13% by weight, and &#x3b3; is preferably in the range of 11% to 13% by weight, and X is preferably about 6% by weight. The chemical formula more preferably is (FeCo)CrSiB. The present invention also relates to a giant magneto-impedance (GMI) based sensing device for non-destructive contactless detection of carburization in austenitic stainless steel samples in field.
