Abstract
Newly developed double spin-detectors system utilizing high-efficient very low energy electron diffraction type spin detector for three dimensional spin vectorial analysis is presented. The high efficiency of the spin detector and the state of the art hemispherical electron analyzer enables us to measure all the spin vector components in high energy- and angular-resolution. The detection of orthogonal three spin components (Px, Py and Pz) are important to observe real spin structure of the Rashba systems or topological insulators that are deviating from the ideal in-plane tangential helical spin structure. In addition three dimensional spin analysis is important for the determination of the degree of spin polarization of such systems since the spin quantization axis of the systems is not obvious unlike the ferromagnetic materials.
