Magnetic Properties of Spin Glass
Spins in a paramagnet fluctuate on the order of 1010 s vs spins in spin glass on the order of s.

The Next steps
I will continue to modify the program, implementing a color gradient to better retrieve data and applying it to spin glass samples.
We will perform field cooling measurements to establish a crossover time.
Time permitting, we will begin to study temperature chaos.
