Abstract :

In this work, the study of superconducting Sr-Ca-Cu-O layered system is presented. Study object is 02(n-1)n compound (critical temperature around 100-110 K) which shows some interesting properties like instability in moisturized air and possibility to entrance of water or carbon into the sample structure between layers. Entrance of alien atoms into the structure may lead to the appearance of some interesting properties like asymmetry in hysteresis M vs. H curves due to the magneticfield irreversibility. The local properties study in both superconducting and block layers may help to clarify the question of air moisture influence on the hyperfine properties of these materials. Hyperfine properties study requires introducing into investigated samples some amount of substituent atoms which is used as a probe. There are several possibilities to add substituent elements inside Sr-Ca-Cu-O superconductor structure: Substitution of a small amount of copper or calcium inside superconducting layers or substitution of a part of strontium atoms inside block layers. Here the effect of introducing of iron and europium into superconducting and block layers was studied. Systems with general formulas of Sr2CaCu1-xFexO6├?┬▒├?┬┤ and Sr2- xEuxCaCu2O6├?┬▒├?┬┤ have been produced and investigated.
