摘要：
The magnetic properties dependent on temperature and external magnetic field in the spin frustrated triangular system are investigated by using Monte Carlo (MC) simulation on a Heisenberg spin model. The single-ion anisotropy with different magnitudes is introduced to scrutinize the variation of magnetic behavior. It is revealed that the strong anisotropy is an essential key to induce the step-like magnetization as a function of magnetic field, as observed in the triangular spin-chain compound Ca3Co2O6 at low temperature. Furthermore, the critical temperature, at which the stepwise magnetic behavior emerges is raised by increasing the anisotropy. This is attributed to the collinear spin structure strengthened by the anisotropy. (C) 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
