A study of the magnetoelastic effect in metallic textured NiW<sub><i>x</i></sub> (x = 5.5, 6.0, 7.4, AND 7.7 at %) ribbons

the dependence of the differential magnetic susceptibility cac(T) of metallic biaxially textured NiWx ribbons with a tungsten content x = 5.5, 6.0, 7.4, 7.7 at% on plane mechanical tension and compressive stresses has been studied in the temperature range 50–350 K. To create the tensile and compressive stresses, the thermal cycling procedure is applied to the ribbons glued to the substrates made of Si and aluminum alloy D16T, respectively. It is shown that the main peculiarities of the magnetic susceptibility behavior can be explained by magnetic orientation transitions and the occurrence of internal stresses s(T) that exceed the elastic limit of NiWx.
