The statistical mechanics of finite L×L Ising square lattices in a field ±h of random sign is investigated numerically by a modified recursive transfer matrix method for 6<~L<~16. Our results are consistent with the absence of a spontaneous magnetization for h≠0 even in the ground state. The singularities occurring at T=0 in the range 0<~h<~4J, J being the exchange constant, are discussed in ...
