Abstract
- The dimerized ferrimagnetic spin chain has been approached both in the presence and absence of the external magnetic field by using the Villain transformation. Two branches of the low-lying energy modes have been presented and the upper branch of the mode demonstrates the exotic omega-shape when the dimerization parameter is greater than 0.6. We also find that the competition between magnetic field and the dimerization parameter also contribute the omega-shape in lower branch mode. Thermodynamic quantities like free energy, specific heat, magnetization, and susceptibility in finite temperature and magnetic field with different dimerization parameters have also been presented.
