Thermodynamics of the two-dimensional frustrated J1-J2 Heisenberg ferromagnet in the collinear stripe regime: Susceptibility and correlation length
M. Härtel, J. Richter, O. Götze +2
We calculate the temperature dependence of the correlation length xi and the uniform susceptibility chi_0 of the frustrated J1-J2 square-lattice Heisenberg ferromagnet in the colli…

Ground-state phase diagram of the spin-1/2 square-lattice J1-J2 model with plaquette structure
O. Götze, S. E. Krüger, F. Fleck +2
Using the coupled cluster method for high orders of approximation and Lanczos exact diagonalization we study the ground-state phase diagram of a quantum spin-1/2 J1-J2 model on the…
