ABSTRACT

Synthesis material Fe (Se,Te) is performed by solid state reaction method with a variety of compositions. Samples containing powder with high purity, 99.99% Fe, 99.99% Se, Te 99.99% was prepared in the glove box and put in a vial of high energy milling and milled by a shaker mill for 2 hours and sintered at a temperature of 773 K for 6 hours. X-ray Diffractometer (XRD) Characterization was conducted to determine the crystal structure and phase are formed and the surface morphology of the material identified using the Scanning Electron Microscope (SEM-EDX). The resistance value of the samples were characterized using Oxford Instruments Cryogenic TeslatronTMCF with a four-point probe method. XRD characterization results obtained sample A has FeSe phase with space group P4/nmm and the surface morphology of the sample similar to the literature. The sample B is a FeTe phase with space group P4/nmm. Sample C did not form the superconducting phase and Sample D has FeSe phase. The quantitative analysis by EDX informed that sample A contains 34.27 at% Fe and 17.41 at% Se. Sample B contains 22.99 at% Fe and 19.18 at% Te. Sample C contains 13.29 at% Fe, 24.33 at% Se, and 3.87 at% Te. Sample D contains 40.87 at% Fe, 21.21 at% Se and 37.91 at% Te. From the test results is known that the resistance of the sample A and B showed the characteristics of superconductors when seen from the graph compared with the literature. While the sample C showed semiconducting properties. For sample D showed superconductor characteristics with values of Tc onset 13,5K, although not yet reached the Tc Zero."

"ASYNNNI model adalah salah satu model yang menerangkan mekanisme pengaturan atom oksigen pada bidang basal senyawa YBa2Cu307-x. Pengaturan atom oksigen pada bidang basal ini sangat mempengaruhi sifat senyawa tersebut. Bila 00.5 bersifat nonsuperkonduktor dengan struktur tetaragonal.

Di samping itu, temperatur juga mempengaruhi sifat superkonduktor. Pada temperatur tertentu (temperatur transisi) ikatan pasangan elektron akan terputus, saat itu sifat superkonduktivitasnya akan menghilang. Temperatur transisi ternyata berubah-ubah dengan berubahnya kandungan oksigen.

Untuk x=0.1 dan x=0.2 temperatur transisi sekitar 90°K, sedangkan untuk x=0.3 dan x=0.4 temperatur transisi sekitar 70°K dan untuk x=0.5 temperatur transisi sekitar 60°K.

Simulasi ini telah menunjukkan adanya perubahan fasa yang ditunjukkan oleh lonjakan harga Cv pada temperatur tertentu.

Simulasi ini menggunakan metode Monte Carlo, sedangkan program yang digunakan bahasa C."

"ASYNNNI model adalah salah satu model yang menerangkan mekanisme pengaturan atom oksigen pada bidang basal (bidang CuO) senyawa BSCCO yang terdiri dari senyawa Bi2Sr2CuO7-x (BSCCO 2201), senyawa Bi2Sr2CaCu2O9-x (BSCCO 2212), dan senyawa Bi2Sr2Ca2Cu3O11-x (BSCCO 2223). Atom-atom oksigen terletak pada lapisan bidang CuO. BSCCO 2201 mempunyai satu lapisan bidang CuO, BSCCO 2212 mempunyai dua lapisan bidang CuO, dan BSCCO 2223 mempunyai tiga lapisan bidang CuO. Pengaturan atom oksigen dan banyak lapisan bidang basal sangat mempengaruhi sifat senyawa tersebut. Senyawa dengan struktur kristal ortorombik bersifat superkonduktor, sedangkan senyawa dengan struktur tetragonal bersifat non-superkonduktor. Temperatur transisi adalah keadaan terjadinya transisi sifat struktur bahan non-superkonduktor ke struktur superkonduktor atau sebaliknya.Temperatur transisi dari perubahan struktur tetragonal ke struktur ortorombik sangat dipengaruhi oleh kandungan oksigen. Temperatur transisi ternyata berubah-ubah dengan berubahnya kandungan oksigen. Telah dihitung temperatur transisi senyawa BSCCO, diperoleh hasil untuk BSCCO 2201 dengan temperatur transisi tertinggi 13.5 K, untuk BSCCO 2212 dengan temperatur transisi tertinggi 83 K, dan untuk BSCCO 2223 dengan temperatur transisi tertinggi 110 K. Simulasi ini telah menunjukkan adanya perubahan fasa yang ditunjukkan oleh lonjakan harga kalor jenis Cv pada temperatur tertentu. Simulasi ini menggunakan metoda Monte Carlo, algoritma Metropolis, dan Glauber Dynamics. Program ini ditulis menggunakan bahasa C."

"ABSTRAKPenelitian ini akan mensimulasikan temperatur transisi pada superkonduktor NdBa2Cu3O7-x. Superkonduktor NdBa2Cu3O7-x terdiri dari satu bidang CuO. Sumulasi temperatur transisi superkonduktor NdBa2Cu3O7-x dapat dipelajari dengan menggunakan model ASYNNNI. Dalam model ASYNNNI, oksigen di tempatkan pada bidang CuO secara acak. Kandungan oksigen yang diberikan akan mempengaruhi besarnya temperatur transisi. Temperatur transisi tertinggi terjadi pada superkonduktor NdBa2Cu3O7-x dengan kandungan oksigen 90% yaitu sekitar 30 K. Temperatur transisi tidak dihasilkan dalam simulasi dua bidang CuO, karena bahan ini tidak bersifat superkonduktor"
