Title : Hall Effect Measurements of the Thin Films Coated with Colloidal Magnetic Particles
Supervisor : DR. Lim Weng Lee
Objective : To investigate the Hall effect in thin films coated with colloidal magnetic particles
Description :
A colloid is basically a chemical mixture in which one type of substance is dispersed almost evenly throughout other substances. In this project, metallic films or non-magnetic semiconducting thin films are coated with colloidal magnetic particles from ferrofluids (or other Ni/Co-based aqueous solution) by using a spinner. The surfactants such as Tetramethylammonium hydroxide or soy lecithin will be used to prepare the films in oder to avoid agglomeration of particles. A procedure to prepare the films with various densities of colloidal magnetic particles will be conducted and the Hall effect measurement on those films will be performed to study their magnetic properties.
Remarks :
Student will learn to handle wet chemicals, spin-coating, curing, and Hall Effect setup. The students are expected to be very vigilant and careful in carrying out laboratory work.
