概要

• 論文の詳細を見る

• A random mixture of two antiferromagnets with magnetic easy plane and easy axis is investigated in the molecular field approximation. The role of the couplings between different species on the details of the phase diagram is studied. It is shown that the smoothness of the intersection of two transition lines at the tetracritical point depends, to some extent, on those couplings. The boundaries between the mixed and XY and Ising phases are less clear than the transitions to the paramagnetic phase.
