Abstract
Human dependence on technology into the Industrial Revolution 4.0 is very high. Example, the application of innovations in information technology is supercomputer from superconducting materials. Superconducting materials are identical from non-ferromagnetic materials because tend perfectly diamagnetic. However, since ferromagnetic-metal-based superconducting material discovered, research continues to be developed, like FeSe superconductor material. Some parameters that need to be considered in making FeSe material to obtain the best superconductor properties include stoichiometric composition, doping addition, and process of making FeSe materials
like synthesis and sintering treatment. In this study, the effect of Mg-doped variations will be analyzed towards properties of superconductors, morphology, and
phases formed in FeSe superconducting materials. MgxFe1-x Se made by solid-state reaction method in sealed tube (Powder in Sealed Tube) “insituely”.
The sintering temperature used 845⁰C which held for 6 hours, with 7⁰C/minute temperature rise from room-
temperature and normalizing cooling rate used. The best candidate superconducting material came from Mg
0.01 Fe 0.99 Se, obtained critical temperature (Tc) onset
= 15.42 K, and Tc zero= 5.4 K. Sample morphology shows a large crystallization. Then,the percentage fraction of the superconducting phase was also the largest, which is 81.99%. |
