Q. 2. (i) N spin-1/2 particles are placed in a B magnetic field. Find the long range order parameter or the magnetization of the system using the cluster change method. For B=0, discuss when the system will become ferromagnetic and paramagnetic, and illustrate by drawing a simple figure. (17.5) (ii) Indicate (show) how, depending on the orientation of the spins, paramagnetic and ferromagnetic antiferromagnetic and ferrimagnetic materials or phases are shown systematically. (2.5/100)
