TY - JOUR AU - Simanungkalit, Suryana Deva PY - 2019 TI - Pengaruh variasi unsur Gd pada struktur kristal superkoduktor Y-358 (Y3-XGdxBa5Cu8O18- δ) JF - Jurnal Teras Fisika: Teori, Modeling, dan Aplikasi Fisika; Vol 2 No 2 (2019): Jurnal Teras Fisika: Teori, Modeling, dan Aplikasi Fisika DO - 10.20884/1.jtf.2019.2.2.1886 KW - N2 - Abstract - Research on the effect of Gd element variations on the Y-358 (Y 3-x Gd x Ba 5 Cu 8 O 18-δ ). Superconducting crystal structure has been carried out. In this study the samples were held in a magnetic stirrer for 24 hours, calcined using a temperature of 600 ° C for 3 hours and sintering using a temperature of 900 ° C for 10 hours. The results of XRD characterization showed sharp peaks that indicate the occurrence of crystallization well. And each sample has the same functional group at a certain wave number. The functional groups found in each sample were Mono Aromatic, Para Aromatic, Ether Alcohol Anhydride, Esters, Nitro Carboxylic Acid (N = O), Alkyl CH (Stretching), Phenol Alcohol, OH Carboxyl Acid (alcohol, phenol, hydrogen bonds).
