Outline of Final Research Achievements

This study consists of developing instrumentation to investigate the dynamic magnetization process of magnetic nano-particles and a series of experiments using such new instrumentation in both time domain and frequency domain. In the time domain, we measured free decay of magnetization induced by a pulse magnetic field. Based on linear transformation theory, such time-domain data can be transformed to those in the frequency domain from which broad-band frequency spectrum can result. Moreover, such measurements in the pulse magnetic field was found to be a rapid and easy-to-use method for the determination of magnetic hysteresis instead of the conventional method with VSM that is usually quite time-consuming.
