Abstract: The magnetic properties of Cs3Fe2Cl9 single crystals were investigated by magnetic and thermal measurements. The crystal structure of Cs3Fe2Cl9 consists of a bilayer triangular lattice of Fe3+ ions. The analysis of magnetic susceptibility clarified that the intra- and interdimer interactions are comparable with each other, and Cs3Fe2Cl9 is regarded as a spin-5/2 J(1)-J(2) buckled honeycomb antiferromagnet with the ferromagnetic interlayer interaction J(3). The susceptibility for the magnetic field H vertical bar vertical bar c axis exhibits a sudden drop at the Neel temperature T-N = 5.4 K, indicating a first-order magnetic phase transition. One of the characteristic features is the linear temperature dependence below TN. Furthermore, Cs3Fe2Cl9 undergoes successive magnetic phase transitions in high magnetic fields along the c axis. We obtained a rich H-T phase diagram in which the M-s/2 magnetization-plateau phase is included. These unique magnetic behaviors probably originate from the competition of magnetic interactions and the easy-axis anisotropy in the antiferromagnetic J(1)-J(2) buckled honeycomb network.
