Relaxation and Magnetization Dynamics of Frustrated Spin-Chain Systems

A 3D model of the magnetization dynamics in frustrated triangular spin-chain systems Ca 3 Co 2 O 6 is proposed. This model is a generalization of the 2D model developed earlier. The spins are assumed to interact with the nearest neighbors and external agency (heat reservoir and external magnetic fie...

Summary:A 3D model of the magnetization dynamics in frustrated triangular spin-chain systems Ca 3 Co 2 O 6 is proposed. This model is a generalization of the 2D model developed earlier. The spins are assumed to interact with the nearest neighbors and external agency (heat reservoir and external magnetic field) that causes them to change their states randomly with time. A probability of a single spin-flip process is assumed in a Glauber-like form. The 3D model allows describing the step-like behavior of a magnetization curves experimentally observed in a strong magnetic field.
