Abstract
Extraordinary magnetoresistance effects /signals/ were investigated in dummy and bubble detectors together with their differences /noises/ in the two sensors as a function of rotating magnetic field. The noise and the signal-to-noise ratio changed with low values of the magnetic field and were practically independent of the field at higher than 2000 Oe. The effect is explained by a difference in the shape anisotropy of the detectors.
