We investigate the uniaxial-pressure dependence of resistivity for URu2-x Fex Si2 samples with x=0 and 0.2,which host a hidden order (HO) and a large-moment antiferromagnetic (LMAFM) phase,respectively.For both samples,the elastoresistivity ζ shows a seemingly divergent behavior above the transition temperature T0 and a quick decrease below it.We find that the temperature dependence of ζ for both samples can be well described by assuming the uniaxial p... 相似文献

Robust Magnetism Against Pressure in Non-Superconducting Samples Prepared from Lutetium Foil and H2/N2 Gas Mixture 下载免费PDF全文
We report the observation of a magnetic transition at the temperature about 56 K, through the high-pressure heat capacity and magnetic susceptibility measurements on the samples that have been claimed to be a nearroom-temperature superconductor [Dasenbrock-Gammon et al. Nature 615, 244(2023)]. Our results show that this magnetic phase is robust against pressure up to 4.3 GPa, which covers the critical pressure of boosting the claimed superconductivity. 相似文献
