Temperature dependence of lower critical field in stripe ordered La1.6-xNd0.4SrxCuO4 superconductors
چکیده انگلیسی


• In this paper, we report detailed measurements of the temperature dependence of the lower critical field Hc1 in the stripe ordered La1.6-xNd0.4SrxCuO4 (x = 0.10 and 0.15) superconductors.
• Hc1(T) of the samples increase with decreasing temperature and an negative curvature below Tc is found.
• The penetration depth λ(T) estimated from Hc1(T) data satisfies a linear temperature dependence behavior below Tc/2, which is consistent with that in a superconductor with d-wave symmetry of the energy gap and the upward trend in Hc1(T) may be due to the cooperation of the hole and election pockets arising from the reconstruction of the Fermi surface, which contributes to illustrating the Fermi surface reconstruction in La1.6-xNd0.4SrxCuO4.
