Bi Layer properties in the Bi-FeNi GMR-type structures probed by spectroscopic ellipsometry
Original language description
Bismuth (Bi) having a large atomic number is characterized by a strong spin–orbit coupling (SOC) and is a parent compound of many 3D topological insulators (TIs). The ultrathin Bi films are supposed to be 2D TIs possessing a nontrivial topology, which opens the possibility of developing new efficient technologies in the field of spintronics. Here we aimed at studying the dielectric function properties of ultrathin Bi/FeNi periodic structures using spectroscopic ellipsometry. The [Bi(d)–FeNi(1.8 nm)]N GMR-type structures were grown by rf sputtering deposition on Sitall-glass (TiO2) substrates. The llipsometric angles Y(w) and D(w) were measured for the grown series (d = 0.6, 1.4, 2.0, and 2.5 nm, N= 16) of the multilayered film samples at room temperature for four angles of incidence of 60, 65, 70, and 75 in a wide photon energy range of 0.5–6.5 eV.
