摘要: We explore, at T = 0, the magnetic properties of S 1/2 antiferromagnetic distorted diamond chain described by Hamiltonian ? j 1N/3{J 1 (S3j?1 ?S3j +S3j ?S3j+1)+J2S3j+1 ?S3j+2 +J3(S3j?2 ?S3j+2)}?H l 1NS lzwith J1, J2, J3 which models well A3Cu3(PO4)4 with A Ca, Sr, Bi4Cu3V2O14 and azurite Cu3(OH)2(CO3)2. employ physical consideration, degenerate perturbation theory, level spectroscopy analysis numerical diagonalization data obtained Lanczos method also density matrix renormalization group (DMRG) method. investigate mechanisms magnetization plateaux M Ms/3 (2/3)Ms, show precise phase diagrams (J2/J1,J3/J1) plane concerned these plateaux, where lz Ms is saturation magnetization. calculate curves means DMRG
