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…
Thermodynamics of the frustrated one-dimensional spin-1/2 Heisenberg ferromagnet in a magnetic field
M. Härtel, J. Richter, D. Ihle
We calculate the low-temperature thermodynamic quantities (magnetization, correlation functions, transverse and longitudinal correlation lengths, spin susceptibility, and specific…
Thermodynamics of a two-dimensional frustrated spin-1/2 Heisenberg ferromagnet
M. Härtel, J. Richter, D. Ihle +1
Using the spin-rotation-invariant Green's function method we calculate the thermodynamic quantities (correlation functions <S_0 S_R>, uniform static spin susceptibility χ, correlat…
Thermodynamics of the frustrated ferromagnetic spin-1/2 Heisenberg chain
J. Richter, M. Härtel, D. Ihle +1
We studied the thermodynamics of the one-dimensional J1-J2 spin-1/2 Heisenberg chain for ferromagnetic nearest-neighbor bonds J1 < 0 and frustrating antiferromagnetic next-nearest-…
