The Mg/MgO/MgB₂ nanocomposite, which is a microscopic and fractal mixture of Mg (metal), MgO (insulator), and MgB₂ (superconductor), has the property that the whole of a system shows superconductivity due to the superconducting proximity effect even when MgB₂ is dilute. In this study, we newly introduced the element Si, a typical semiconductor, into this Mg/MgO/MgB₂ nanocomposite and investigated the effect of Si addition on the superconducting properties of the Mg/MgO/MgB₂ nanocomposite.
