Abstract: 
The magnetoresistance (MR) effect of the low-temperature phase of silver selenide (alpha-Ag2+deltaSe) is measured as a function of composition. Very small composition variations in the order of Deltadelta=10(-6) are achieved by coulometric titration and can be performed simultaneously during the MR measurement. A homogeneous Ag2+deltaSe shows an ordinary magnetoresistance (OMR) effect, which can be well described by the two-band model. For silver selenide with a heterogenous silver excess, we found quite a different MR behavior. Up to a minor silver excess of 1x10(-4)10(-2)) shows again an OMR effect.
