Dynamics of magnetization in frustrated spin-chain systems: Ca${}_3$Co${}_2$O${}_6$

Abstract

The magnetization dynamics of the triangular lattice of Ising spin chains is investigated in the framework of a two-dimensional model. The rigid chains are assumed to interact with the nearest neighboring chains, an external magnetic field, and a heat reservoir that causes the chains to change their states randomly with time. A probability of a single spin-flip process is assumed in a Glauber-like form. This technique allows describing properly the steps in the magnetization curves observed in Ca${}_3$Co${}_2$O${}_6$ and their dependence on a magnetic field sweep rate and temperature. A transition from a low-temperature to high-temperature phase is also observed.
