Molecular Magnetism This Web site is dedicated to the international community of Molecular Magnetism Scientists. Contained in these pages are lists of researchers, recent research developments, upcoming events, postdoctoral openings, and a reference database. VRML Gallery of Electromagnetism (by Rob Salgado) THE PRINCIPLE OF SUPERPOSITION Classical Electricity and Magnetism, 2nd edition Hysteresis-loop Java Applet simulating Hysteresis loop of a ferromagnetic particle. The Energy-density of a ferromagnetic particle is calculated while a magnetic field H is applied to the particle. Searching the local minimum of the energy provides the angle that the magnetization forms with the easy-axis. The Hysteresis-loop is a result of the variation of the applied field. SWaves Provides a simple graphical depiction of spin waves on a two-dimensional lattice. The applet shows a 6-by-6 array of precessing spins. Each of these precessing moments obey the same equations of motion as the magnetization vector shown in the previous applet. For simplicity, damping has been eliminated in this model. FMR The applet below gives a simple demonstration of both a frequency-swept and a field-swept FMR experiment. The plot shows the microwave power absorbed as a function of either frequency or field. The power is proportional to the square of the amplitude of the precession. Try both ways, and then try changing the damping to see the effect on the absorption spectra. Pressing Finish will stop the applet execution.
