Ferromagnetic energy

Assume an Ising model on a square lattice oiN = L X L spins. At site k on the lattice the possible spin orientations are = 1. Neighbor spins m and I interact with ferromagnetic energy > 0) and the reciprocal temperature is defined by K = With the SM method one starts from an empty...

Other. Alkali chiorochromate compounds, including cesium chiorochromate, CsCrCl, are ferromagnetic substances being studied for potential apphcation in optically-read computer memory devices. Cesium has also been used in vapor glow lamps (44), vapor rectifiers, and high energy lasers (qv)...
