Some Preliminary Investiagtions of the Magnetic Permeabilities of Alloys of the Ferromagnetic Metals

The problem presented for this thesis was an investigation of the magnetic properties of the alloys produced by the methods of powder metallurgy. The question behind this was the correlation of the magnetic properties with the bonding properties and with the diffusion of the constituents.

Measurements of the Magnetic Permeabilities of the Iron-Manganese Alloy System Prepared by the Methods of Powder Metallurgy

Powder metallurgy is a branch of metallurgy which produces metallic compacts in their final forms by means of pressure and heat-treatment from the pow­ders. The products of powder metallurgy are being used in our daily lives quite often. For example, the tungsten wires in the electric bulbs to the silver-tin fillings of our teeth.

A Study on the Fluorescent Properties of Nanoapatite Particles Under Externally Applied Magnetic Fields

Hydroxyapatite is a naturally occurring mineral found in human bones and teeth. Its chemical formula is: Ca10(PO4)6(OH)2. In this project hydroxyapatite nanoparticles were doped with iron or europium to give the particles magnetic or fluorescent properties, respectively. The magnetic and fluorescent responses of these particles under externally applied magnetic fields has not yet been fully characterized.
