Abstract
Relating to a thin film lamination and a thin film magnetic sensor using the thin film lamination and a method for manufacturing the thin film lamination that realizes a thin film conducting layer having high electron mobility and sheet resistance as an InAsSb operating layer. A thin film lamination is provided which is characterized by having an AlInSb mixed crystal layer formed on a substrate, and an InAsSb(0<x≦1) thin film conducting layer directly formed on the AlInSb layer, in which the AlInSb mixed crystal layer is a layer that exhibits higher resistance than the InAsSbthin film conducting layer or exhibits insulation or p-type conductivity, and its band gap is greater than the InAsSbthin film conducting layer, and the a lattice mismatch is +1.3% to −0.8%.
