To make a direct observation of the stress sensitivity on the ribbons，we further tested piezomagnetic property of Fe73.5Cu1Nb3Si13.5B9 ribbon with different thickness，which is exhibited in Fig.11.All sets of ribbons present a similar variation:at the beginning of loading，the inductance shows a rapid rising，i.e.the sensitive range，after which，the inductance of the ribbon continue has small changes with the stress increasing，but the variation amplitude is much less than that in the week regime.The sample c with 31~33μm is different，whose inductance value gradually drops with the pressure enhancing after the initial rise，which is called the negative piezomagnetic property.This specific mechanism remains to be further explored.The sensitive range of sample a~d determined by amplification method is0~0.33，0~0.35，0~0.44 and 0~1.20 kPa，respectively.Comprehensive analyses of each sample situation of the piezomagnetic properties are listed in Table 1.
