Magnetic saturation of poly(dimethyl-siloxane) matrix composites based magnetorheological elastomers

Abstract

The most common used parameters in applications of magnetorheological elastomers are characteristic data of magnetization curve. Vibrating sample magnetometer (VSM) is a unique technique to record the magnetization curve of small samples. From measurement data the further calculations have to be done for determination of the saturation magnetisation as among other factors some materials can not be saturated with this VSM, but the saturation magnetization can be determine as the fitted curve´s parameter. It was found, that the saturation magnetisation depends on filling factor (as rate of components). To get composite saturation magnetisation components saturation magnetisation in proportion of their weight percentage should summing-up. The knowledge of error limits presents a usable tool for further examination.
