Document Summary

Mse 3321, electronic properties 9, april 20, 2016. Finish by the end of next class on friday (april 22) and turn in. Names: cameron contairo, maggie van keuls, kate powers: please complete your sei evaluation for this class now, in case you haven"t done it yet. Thank you: domain structure (a) define in one sentence what a magnetic domain is in a ferromagnetic material. [colors optional to your liking] plot the spin distributions for 100 k, 200 k, and 300 k and report the resulting magnetization (relative to msat(0), which is the default output of the program). c. i. Hint 1: you can use the if command to find all points with equal spin and store its coordinates (ix,iy) in x- and y-vectors. c. ii. Hint 2: markerfacecolor","r" fills a symbol with red in the plot command. c. iii. Change the size of your plotting window until the squares touch seamlessly and produce a plot similar to this:
