Effect of thermal annealing on the magnetic properties of Hastelloy C-276 alloy with intermediate Al2 O3 /Y2 O3 /MgO/LaMnO3 buffer layers I. V. Yanilkin, A. I. Gumarov, D. S. Uvin, A. G. Kiiamov, S. A. Khokhorin, et al. Uchenye Zapiski Kazanskogo Universiteta Seriya Fiziko Matematicheskie Nauki, 2025 This article presents the results of an experimental study on the surface morphology, elemental composition, and magnetic properties of Hastelloy C-276 substrates with intermediate Al2O3/Y2O3/MgO/LaMnO3 buffer layers and a deposited MgB2 superconductor. Measurements were carried out at a magnetic field from −5 to 5 T and in the temperature interval from 5 to 15 K, with the annealing temperatures of the tapes in the range from 623 to 923 K. Vacuum annealing had a significant effect on the magnetic characteristics of the substrates, and the specific magnetic moment varied up to 20 % depending on the annealing temperature in the temperature interval from 5 to 15 K.
Synthesis of MgB2 films on Hastelloy-C276 tape with Al2O3/Y2O3/MgO/LaMnO3 buffer layers by magnetron sputtering in co-evaporation mode I V Yanilkin, A I Gumarov, I A Rudnev, L R Fatikhova, A G Kiiamov, et al. Superconductor Science and Technology, 2024 This study presents the initial results of developing a technology for synthesizing a flexible superconducting magnesium diboride composite on a Hastelloy®-C276TM substrate coated with Al2O3/Y2O3/MgO/LaMnO3 buffer layers. The superconducting composite was deposited by magnetron sputtering from two Mg and B targets, followed by vacuum annealing at various substrate temperatures ranging from 400 °C to 700 °C. The superconducting transition temperature T c ≈ 22 K, with a transition width ΔT ≈ 1 K, and critical current J c ≈ 500 kA cm−2 (T= 5 K, H = 2 T) and J c ≈ 11 kA cm−2 (T = 15 K, H = 2 T) at the optimal annealing temperature of 400 °C.
