Title : Quantum phase transitions in frustrated two-leg spin ladder model for nanostructured complexes of transition metals

Abstract:

The ground state properties of the frustrated two-leg spin ladder model for nanostructured magnetic materials on the base of transition metal complexes have been studied. Using perturbation theory and numerical methods we found the possibility of quantum phase transitions, mediated by the value of the interactions between neighbouring ladder rungs. These phase transitions are characterized by significant change of the spin ordering in the ground state and are central to potential applications in molecular spintronics.

Audience take-away:

  • It is shown, that the theoretical approach based on spin formalism of valence bond method of quantum chemistry is of interest for the explanation of the relationship between chemical structure and magnetic properties of nanomaterials.
  • The results of above study will be useful for targeted design of the new magnetic materials on the base of transition metal complexes for needs of molecular spintronics. In particular, sensitivity of the spin ordering in the ground state of the proposed model nanomagnets to the chemical surrounding can be used for the design of new chemosencors.
