Overview

Experimental Condensed Matter Physics

Ph.D., Northeastern University, 1986

Professor Hamdeh's research in experimental condensed matter physics focuses on magnetic materials in different forms and states. These systems include bulk, nano-size particles, and thin films of soft and hard magnets, ferrites, and magnetic oxides. Other interests include nano-particle catalyst. The primary techniques for studying these materials are magnetic susceptibility and Mössbauer spectroscopy in high magnetic fields and at temperatures ranging from 4.2 to 1000 K. The goal of his work is to correlate the physical magnetic properties to the state of materials and the size growth of nano-scale particles. Dr. Hamdeh has published over 100 articles and presented an equal number of papers at national or international conferences.
