Influence of Magnetic Anisotropy on Quantum Spin Systems

Opis projekta

Study of magnetic materials provides us with understanding many of physical phenomena and continues to provide us with new technologies. Magnetism is a quantum phenomenon emerging from the superexchange interactions between magnetic moments in the material. Understanding how these interactions bring forth a material with specific magnetic properties is one of the key questions in materials science. In low-dimensional quantum spin systems the interactions between the spins are often described by the isotropic Heisenberg Hamiltonian. The importance of weak anisotropic interactions emerges from experiments and requires new theoretical treatments. These interactions are found to induce new interesting phenomena with great potential for applications in emerging technologies. Exploiting new methods sensitive to these interactions is thus crucial. Aim of this project is to experimentally investigate the influence of magnetic anisotropy on chosen quantum spin systems by combining two highly sensitive techniques: torque magnetometry and electron spin resonance (ESR) spectroscopy. Our study is focused on samples with magnetism coming from electron spin S=1/2, which can be classified as weakly interacting small spin clusters, quasi one-dimensional Heisenberg antiferromagnets and/or magnetoelectrics. The combination of mentioned techniques allows a new methodology for investigation of the influence of magnetic anisotropy on quantum spin systems and other magnetic materials and will provide important input in understanding of anisotropy induced phenomena. Within this project a collaboration between physicists and a chemist will be established with the purpose of synthesising new high-quality magnetic materials. Our study will focus on these materials, and on samples synthesized in expert laboratories abroad. The main aim of this project is to form a new independent research group highly qualified to investigate the anisotropy induced phenomena in new promising magnetic materials.
