Thermodynamic Properties of Weakly Anisotropic Disordered Magnetic Chains in the Large-S Limit
I. Avgin, D. L. Huber
we investigate the thermodynamic properties of weakly anisotropic disordered magnetic chains where the nearest-neighbor Heisenberg exchange coupling is the dominant spin-spin inter…
Quantum generalized constant coupling model for geometrically frustrated antiferromagnets
A. J. Garcia-Adeva, D. L. Huber
A generalized constant coupling approximation for quantum geometrically frustrated antiferromagnets is presented. Starting from a frustrated unit, we introduce the interactions wit…
Magnetic properties of the frustrated AFM spinel ZnCr_2O_4 and the spin-glass Zn_{1-x}Cd_xCr_2O_4 (x=0.05,0.10)
H. Martinho, N. O. Moreno, J. A. Sanjurjo +9
The -dependence (2- 400 K) of the electron paramagnetic resonance (EPR), magnetic susceptibility, , and specific heat, , of the antiferromagnetic (AFM)…
Quantum tetrahedral mean field theory of the magnetic susceptibility for the pyrochlore lattice
A. J. Garcia-Adeva, D. L. Huber
A quantum mean field theory of the pyrochlore lattice is presented. The starting point is not the individual magnetic ions, as in the usual Curie-Weiss mean field theory, but a set…
