Abstract

The enhancement of superconductor compounds contribute in reducing the heat pollution that gain from electric transfer. The main focus of all researchers pointed on high temperature superconductors where they aim to get higher critical temperature. This research focus on investigations the concurrent substitution effect Yttrium at the Barium site of HgBa2Ca2Cu3O8+δ superconductor for x=0, 0.1, 0.2 and 0.3, The samples were prepared using a solid-state reaction technique and all samples were exposed to XRD so as to know the crystal structure and its lattice constants. XRD data collected from different samples showed that represents high critical phase and the analysis presents a tetragonal structure. To find the critical temperature 4 probe technique was adopted using relationship electrical resistance and temperature. It was observed that there was a critical temperature rise with the increase of strontium from 95 K to 120 K.The enhancement of superconductor compounds contribute in reducing the heat pollution that gain from electric transfer. The main focus of all researchers pointed on high temperature superconductors where they aim to get higher critical temperature. This research focus on investigations the concurrent substitution effect Yttrium at the Barium site of HgBa2Ca2Cu3O8+δ superconductor for x=0, 0.1, 0.2 and 0.3, The samples were prepared using a solid-state reaction technique and all samples were exposed to XRD so as to know the crystal structure and its lattice constants. XRD data collected from different samples showed that represents high critical phase and the analysis presents a tetragonal structure. To find the critical temperature 4 probe technique was adopted using relationship electrical resistance and temperature. It was observed that there was a critical temperature rise with the increase of strontium from 95 K to 120 K.

用钇部分取代钡对HgBa2-xYxCa2Cu3O8+δ超导化合物的影响
超导体化合物的增强有助于减少电传递带来的热污染。所有研究人员的主要焦点都指向高温超导体,他们的目标是获得更高的临界温度。本研究重点考察了x=0、0.1、0.2和0.3时HgBa2Ca2Cu3O8+δ超导体钡位上钇的同步取代效应。采用固相反应技术制备样品,并对样品进行XRD分析,了解样品的晶体结构和晶格常数。不同样品的XRD数据表明,该材料为高临界相,呈四边形结构。利用电阻与温度的关系,采用4探针技术寻找临界温度。当锶从95 K增加到120 K时,有一个临界温度上升。超导体化合物的增强有助于减少电传递带来的热污染。所有研究人员的主要焦点都指向高温超导体,他们的目标是获得更高的临界温度。本研究重点考察了x=0、0.1、0.2和0.3时HgBa2Ca2Cu3O8+δ超导体钡位上钇的同步取代效应。采用固相反应技术制备样品,并对样品进行XRD分析,了解样品的晶体结构和晶格常数。不同样品的XRD数据表明,该材料为高临界相,呈四边形结构。利用电阻与温度的关系,采用4探针技术寻找临界温度。当锶从95 K增加到120 K时,有一个临界温度上升。
