Thermal properties of ferrimagnetic systems
Aiman Al-Omari, A. H. Nayyar
The heat capacity of some ferrimagnets has additional structures like a shoulder in the Schottky-like peak, or emergence of a second peak when an external magnetic field is applied…
Combined effect of frustration and dimerization in ferrimagnetic chains and square lattice
Aiman Al-Omari, A. H. Nayyar
Within the zero-temperature linear spin-wave theory we have investigated the effect of frustration and dimerization of a Heisenberg system with alternating spins and $s_{2}…
Dimerization of Ferrimagnets on Chains and Square Lattices
Aiman Al-Omari, A. H. Nayyar
A linear spin wave analysis of dimerization of alternating Heisenberg system with spins and on linear chain as well as square lattice is presented. Among the severa…
Spin-Peierls Dimerization of a s=1/2 Heisenberg Antiferromagnet on a Square Lattice
Aiman Al-Omari
Dimerization of a spin-half Heisenberg antiferromagnet on a square lattice is investigated for several possible dimerized configurations, some of which are shown to have lower grou…
Spin-Peierls Dimerization of a s=1/2 Heisenberg Antiferromagnet on Square Lattice
Aiman Al-Omari, A. H. Nayyar
Dimerization of a spin-half Heisenberg antiferromagnet on a square lattice is investigated by taking unexpanded exchange couplings. Several dimerized configurations are considered…
