ABSTRACT:
A stress-sensitive sensor comprising a means for generating magnetic flux, a thin sheet of an amorphous magnetic alloy which is located in the magnetic flux and which is physically deformed in response to an external force to be measured, and a means for detecting the physical deformation as a variation of the magnetic flux which depends on the external force. The amorphous magnetic alloy consists essentially of Fe.sub.a Cr.sub.b Si.sub.c B.sub.d, in which a is a value of from 69 to 81.5 atomic percent, b is a value of from 2.5 to 6 atomic percent, c is a value of from 10 to 15 atomic percent, and d is a value from 6 to 10 atomic percent provided that a+b+c+d=100. The sensor is particularly suitable for oil pressure or torque detection.
