Therefore, the polarization extinction ratio was greatly improved compared with the samples without doping.CubicPm-3nNb3Sn0.92superconductor (Tc∼ 16 K) was found to exhibit tetragonal instabilities at the superconducting state (T= 10 K). These instabilities are manifested through the appearance of reflections which are forbidden in thePm-3nsymmetry but are compatible with theP42/mmcstructure which is observed in the Nb3Sn1-xsystem for higher Sn content at temperatures lower than ∼43 K. Nevertheless, the low-temperat
