The magnetoresistance curves of quench-condensed granular Ni very close to the electric percolation threshold exhibit sharp reproducible resistance jumps. These have been interpreted as signs for magneto-mechanical effects which occur in the magnetic particles due to interactions with the surrounding grains. In this paper we present additional experimental results that are consistent with a model in which the grains that act as bottlenecks in the resistance network exhibit buckling-like magneto-mechanical distortions leading to a resistance increase.
