摘要
In this work, we aim to study both analytically and numerically the behavior of triangular spin tubes made by three chains which are connected to one another by exchange, in the presence of single-ion anisotropy. By diagonalizing the spin Hamiltonian, the partition function was exactly calculated within the transfer matrix approach and several relevant physical quantities were derived and analyzed. Depending on the sign and strengths of the exchange and anisotropy constants, the system reveals a rich variety of features such as frustration and steplikes in the magnetization curves arising from both geometry and conflicting interactions.
