CONTINUOUS- AND FIRST-ORDER PHASE TRANSITIONS IN ISING ANTIFERROMAGNETS WITH NEXT-NEAREST- NEIGHBOUR INTERACTIONS

Both the square and triangular (sing antiferromagnetic systems with next-nearest neighbour interactions are studied by a new efficient entropic scheme. Using the energy distribution and order parameter's fourth order cumulant it is illustrated that the two models behave quite differently. For t...
