Effect of thermal annealing on the magnetic properties of Hastelloy C-276 alloy with intermediate Al2O3/Y2O3/MgO/LaMnO3 buffer layers
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 Al 2 O 3 /Y 2 O 3 /MgO/LaMnO 3 buffer layers and a deposited MgB 2 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.
