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.
Highlights
The size and shape of nano-particle as well as the environment are important parameters in determining the properties of the nano-particle

In this work graded helical square tower-like terrace shaped sculptured thin films (GHSTTS) were produced by oblique angle deposition together with the rotation of the substrate sequentially by 90°, while a shadowing block was fixed at the centre of the substrate holder having substrates
Summary
The size and shape of nano-particle as well as the environment (medium) are important parameters in determining the properties of the nano-particle.
