英文摘要	Magnetic properties of the t-J model in two-and three-dimensional lattices are investigated by a systematic method. The quasiparticle picture, and in particular, dispersion relations of holons and renormalized spinons are presented explicitly. Results are compared with that of numerical simulations and they are in qualitative agreement. The expression of low-temperature magnetization gives a reasonable explanation for the strange phenomena of doping enhancement of the half-filled antiferromagnetic ground state at low temperatures, which was discovered years ago in neutron-scattering experiments. Features at the phase transition region predict antiferromagnetic-metallic transition and give an expression for the doping-dependent Neel temperature.
