Energy spectrum and thermodynamics of quasi-one-dimensional ferrimagnets on the basis of transition metal compounds
The study of energy spectrum of necklace spin ladder modelling magnetic properties of a number of quasi-one-dimensional ferrimagnetics containing ions of transition metals, was carried out. It was shown that the excitations without decrease of total spin are separated from ground state by finite ene...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The study of energy spectrum of necklace spin ladder modelling magnetic properties of a number of quasi-one-dimensional ferrimagnetics containing ions of transition metals, was carried out. It was shown that the excitations without decrease of total spin are separated from ground state by finite energy gap, and the excitations with decrease of total spin are gapless. Temperature dependence of magnetic susceptibility, agreed with known experimental data for quasi-one-dimensional Cu-Ni bimetallic ferrimagnets and analytical formula for Ising model of NL, was built on the base of exact energy spectra of small ladder clusters. |
