Title: Versatile strain-tuning of modulated long-period magnetic structures

Journal Article · · Applied Physics Letters
DOI:https://doi.org/10.1063/1.4983473· OSTI ID:1357131

We report the design of a versatile strain cell for small angle neutron scattering (SANS) unique in its ability to select the application of either or tensile compressive strain in-situ. Strain is applied to the sample via two independently actuated copper pressure transducers that can each apply a mechanical force of 270 N onto the sample using helium gas pressure. The strain cell is optimized for magnetic SANS on modulated long-period magnetic structures, and is therefore compact enough to t in common sample environments, such as low-temperature cryostats and superconducting magnets. In this report we have successfully utilized the described strain cell to investigate the response of the skyrmion lattice in MnSi.
