| 中文摘要 | We use neutron scattering to study the effect of uniaxial pressure on the tetragonal-to-orthorhombic structural (T-s) and paramagnetic-to-antiferromagnetic (T-N) phase transitions in NaFeAs and compare the outcome with similar measurements on as-grown and annealed BaFe2As2. In previous work on as-grown BaFe2As2, uniaxial pressure necessary to detwin the sample was found to induce a significant increase in zero pressure T-N and T-s. However, we find that similar uniaxial pressure used to detwin NaFeAs and annealed BaFe2As2 has a very small effect on their T-N and T-s. Since transport measurements on these samples still reveal resistivity anisotropy above T-N and T-s, we conclude that such anisotropy can not be due to uniaxial strain-induced T-N and T-s shifts, but must arise from intrinsic electronic anisotropy in these materials. |
