Orientation selection and superconducting properties of epitaxial Al on ferromagnetic semiconductor (In,Fe)As
Hirotaka Hara, Keita Ishihara, Masaaki Tanaka +1
Superconductor/ferromagnet heterostructures provide a versatile platform for exploring spin-dependent superconducting phenomena arising from interfacial proximity effects. In this…
Interplay of superconductivity and ferromagnetism in ferromagnetic semiconductor-based Josephson junctions
Hirotaka Hara, Lukas Baker, Axel Leblanc +8
The interplay between superconductivity and ferromagnetism has long been pursued as a route to unconventional Josephson effects, yet suitable material platforms remain limited. Her…
Allotropic transition of Dirac semimetal α-Sn to superconductor β-Sn induced by irradiation of focused ion beam
Kohdai Inagaki, Keita Ishihara, Tomoki Hotta +9
Diamond-type structure allotrope α-Sn is attracting much attention as a topological Dirac semimetal (TDS). In this study, we demonstrate that α-Sn undergoes a phase transition to a…
Giant superconducting diode effect in ion-beam patterned Sn-based superconductor nanowire / topological Dirac semimetal planar heterostructures
Keita Ishihara, Le Duc Anh, Tomoki Hotta +3
Superconductor/topological material heterostructures are intensively studied as a platform for topological superconductivity and Majorana physics. However, the high cost of nanofab…
