Simulation

R=2.0


This space contains a Java applet

If you are seeing this, it is because your browser does not support java, or because you have turned off java support in your browser. Netscape Communicator supports Java on many platforms.
The panel on the left displays the lattice, spins are colored blue when down and colored green when up; clusters of spins flash red when they flip. The panel on the right is a plot of magnetic field (horizontal) versus magnetization (vertical.) The applet will run the model to the maximum and minimum magnetic fields to generate a hysteresis loop; after that, you can tell the applet to run the model to a particular magnetic field by clicking on the control bar underneath the plot.

At R=2.0 you will observe mostly small avalanches. After the model has plotted a hysteresis loop, try running the model part way and reversing it.

Go back to the model's home page to try a different random field.
