Abstract
The decorated Ising model is a modifcation of the Ising model that allows for non- Ising intermittent spins to be inserted into a lattice of Ising spins at uniform intervals. Like the Ising chain, the decorated Ising chain is exactly solvable, which allows for novel modeling possibilities. This thesis introduces the superspin model, a decorated chain with single-spin decorations, and a Java-based computer simulation that demonstrates the properties of this model. The simulation models a microcanonical superspin system using the demon algorithm. The program models spin systems by producing color-coded animated graphics and statistical information at the end of each run. The simulations results agree well with theoretical values calculated using the partition functions for the Ising chain and the superspin model.
