Abstract

The magnetic penetration depth ߣ is one of the most fundamental parameters of superconductivity which is the order of several hundred angstroms. Thus in this work, temperature behavior of the penetration depth has been investigated. At first Gorter-Casimir two fluid model is viewed. Due to importance of the BCS energy gap, it appears that in high temperature superconductors (HTS) penetration depth is different from the two fluid model. At low temperatures, the condition of ܶ/ܶ௖ ൑ 1/3, unconventional superconductors variation of penetration depth with temperature was compared with available literature results..
