The characteristics of a chevron stretcher detector consisting of a thin permalloy bar (200–900Å thick) placed transverse to a multiple chevron track are presented for frequencies up to 100 KHz. Data has been taken at quasi‐static and high frequencies on the output as a function of bias field, detector current, in‐plane field and the length of bubble stretching. The characteristics of the bubble signal were also observed as a function of the rotating field and the length of bubble stretching. The characteristics of the bubble signal were also observed as a function of the rotating field direction for detector elements at two positions on the chevron propagation track. The data indicates that the position is very important in determining the structure of the bubble signal. The output drops off with increasing bias and drive field and can be found to vary with frequency depending upon the value of the in‐plane drive field. The output is also linear with the length of bubble stretching.
