Abstract

Mn sculptured thin films were fabricated in form of graded helical square tower-like terraced sculptured Mn thin films GHSTTS using oblique angle deposition together with rotation of substrate about its surface normal with fixed rotation angle 90° and a shadowing block which was fixed at the centre of the substrate holder. The anisotropy of the samples was examined by resistivity measurements at two orthogonal angles. Direct relationship is obtained between resistivity and the anisotropy of the produced samples which showed that both of these parameters increase with decreasing distance from the edge of the shadowing block. Simulation work using the perturbation theory produced results consistent with the experimental observations.
