Nematicity in LaFeAsO single crystals studied by elastoresistance, high-resolution thermal expansion and shear-modulus measurements
X. C. Hong, S. Sauerland, L. Wang +10
Nematicity in LaFeAsO single crystals is studied by means of high-resolution thermal expansion, shear modulus, and elastoresistivity measurements. A softening of the shear modulus…

A Cryogenic Uniaxial Strain Cell for Elastoresistance Measurements
Franz Eckelt, Isidoro Cavallaro, Ralph Wagner +5
We present the design, implementation, and validation of a cryo-compatible strain cell for elastoresistance measurements in quantum materials. The cell is actuated by three large-f…
