Assume you have magnetic molecules on the distinguishable corners of a cube. The magnetic moment of each molecule can either point up or down (but not sideways). Sketch the system (i.e., a cube with molecules at each corner). Under a certain magnetic field, the energy of the system is 20 meV times the absolute value of the difference between the number of the down pointing and up-pointing magnets molecules. [Ei=20meV*|Niup-Nidown|] Make a table of the energetic states of the system and their degeneracy. Write the canonical partition function of the system. Plot its internal energy as a function of temperature in the regime near the ‘characteristic’ temperature of this system.
