Notes:
Unexpectedly large increases in longitudinal elastoresistance γ=(1/Δe)(ΔR/R0) with decrease in temperature have been reported in the past for thin films of silver (thickness/carrier mean free path ≥1) on mica substrates. Here we subject such samples to electrically induced strain modulation, in the presence of large static strains. We trace the observed increases in γ to an anomalously large nonlinear response of the film resistivity to strain. Isolated from other experimental contributions, this nonlinearity by itself is temperature insensitive. Auxiliary experiments indicate that the anomaly persists for arbitrary combinations of applied planar strains. The data suggest that the large effect is caused by the nonlinear response under large strains of the scattering of carriers by structural defects such as grain boundaries.
