Exchange-bond structure and magnetization-step spectra of a diluted Heisenberg antiferromagnet on the square lattice: Lopsided two-exchange models
Yaacov Shapira, Valdir Bindilatti
Theoretycal results on the magnetization and susceptibility of a Heisenberg diluted antiferromagnet in the square lattice are given. The models considered have two exchange constan…

Magnetization steps and cluster-type statistics for a diluted Heisenberg antiferromagnet on the square lattice: Models with two exchange constants
Yaacov Shapira, Valdir Bindilatti
The paper presents theoretical results on the magnetization of a diluted Heisenberg antiferromagnet on the square lattice for models with two exchange constants (J1-J2 and J1-J3).…
