Abstract
For the chevron stretcher detectors usually employed, the fractional change in resistivity decreases compared to a detector bar without stretcher. By positioning the sensor between the gap of two successive chevron columns so that no metallic contact exists between bars and sensor, this decrease can be avoided. Characteristics of this improved gap detector are presented. Using an 11‐fold chevron stretcher the bridge signal is 0.9 mV/mA for 9μm bubble domains. The overall ’’ONE’’ to ’’ZERO’’ ratio is about 5:1 at 100 kHz drive field frequency.
