Abstract

For two-dimensional magnets with frustrated interactions that prevent magnetic ordering, it is believed that a state without any magnetic long-range order, called a spin liquid, may be realized in the ground state. Quasiparticles created from such a spin liquid may be different from conventional elementary excitations based on classical magnetic orders. In this article, we report theoretical results showing that various anomalous features observed in the anisotropic triangular antiferromagnet Cs_2CuCl_4 can be explained in a unified manner in terms of quasiparticles that are not based on classical magnetic orders.
