Measurement of the elastoresistivity coefficients of the underdoped iron arsenide Ba(Fe sub(0.975) Co sub(0.025)) sub(2) As sub(2)

A new method is presented for measuring terms in the elastoresistivity tensor m sub(ij) of single crystal samples with tetragonal symmetry. The technique is applied to a representative underdoped Fe-arsenide, Ba(Fe sub(0.975) Co sub(0.025)) sub(2) As sub(2), revealing an anomalously large and anisot...
