Abstract
The amorphization of the spin 1/2 transverse Ising model is studied wi thin the effective field theory. General formulae, applicable to struc tures with arbitrary coordination number N are given. Results for the phase diagram and the temperature dependence of the longitudinal and t ransverse magnetizations are presented for a cubic lattice with N = 6. A number of interesting phenomena is found in these quantities, due t o the fluctuation of exchange interactions and the applied transverse field.
