The starting materials which consisted of iron, selenium, and tellurium powder were weighed in the stoichiometry ratio Fe:Se = 1:1 and Fe:Se:Te = 1:0.5:0.5. The starting materials were ground using an agate mortar for 3 h in the air. The milled powders were separated into 2 variations respectively the vacuum and powder in a sealed tube (PIST) method. For the vacuum method, the milled powders were weighed and compacted with a pressure of 165 MPa using a hydraulic press machine to form a pellet shape. For another method, the milled powders were inserted into the stainless-steel (SS316) tube and then compacted. Finally, the pellet and compacted tube were then sintered at the temperature of 745°C and 845°C for 3 h and left in the furnace to room temperature. Based on the resistivity measurement, the best sample was obtained in the FeSe0.5Te0.5 sample that sintered at the temperature of 745°C using the vacuum method. The critical temperature onset (Tconset) and critical temperature zero (Tczero) of the best sample were found at 16.66 K and 7.5 K, respectively.","PeriodicalId":412317,"journal":{"name":"THE 1ST INTERNATIONAL CONFERENCE ON PHYSICS AND APPLIED PHYSICS (THE 1ST ICP&AP) 2019: Fundamental and Innovative Research for Improving Competitive Dignified Nation and Industrial Revolution 4.0","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116756096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The improvements of this material have been made by atom substitutions as well as methods of preparation. The different number of CuO layers in Tl-based cuprate can be used to investigate the effect of different numbers of Cu–O layers as well as the role of agent doping in the mechanism of superconductivity in the cuprates. By using conventional method, the addition of Cr to (Tl1-xCrx) Sr2CaCu2O7-δ with x= 0.0, 0.05, ..., 0.20; critical temperature in the range of 91K to 105K. The (Tl1-xRhx) Sr2CaCu2O7-δ showed changes in room-temperature resistivity and sample with x = 0.20 showed the highest Tc-onset (91K). The electrical resistivity of (Tl1−xCrx) Ba2Ca2Cu3O9−δ for x = 0.4–0.8 samples showed Tc-onset at around 124K. Samples with nominal starting composition Tl2Ba2CaCu2O8 (CdTe)x with x = 0 to 0.20 weight percent (wt.%) have been prepared by the solid-state reaction method. The critical onset temperature, Tc-onset for all samples was between 104K and 108 K while the critical zero resistance temperature, Tc-zero was from 93K to 95K. It was found that the addition of nano Ag decreased the critical temperature and phase formation of (Tl0.85Cr0.15) Sr2CaCu2O7-δAgx. HTSC (Tl2-xCrxBa2CaCu2O8-δ) showed a Tc-zero of 96K and Tc-onset 116K for x = 2. Whereas a high Tc-zero of 100K and Tc-onset of 115K was found in (Tl1.9Te0.1Ba2CaCu2O8δ) system. Based on the most results of experiments, it can be concluded that TBCCO with toxic precursor is in high temperature superconductor. The presence of doping agent was effective only in a few moles. It was observed that phase formation affected the critical temperature.","PeriodicalId":412317,"journal":{"name":"THE 1ST INTERNATIONAL CONFERENCE ON PHYSICS AND APPLIED PHYSICS (THE 1ST ICP&AP) 2019: Fundamental and Innovative Research for Improving Competitive Dignified Nation and Industrial Revolution 4.0","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130282871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
