| 中文摘要 | the thermodynamic properties of the spin-1/2 diamond quantum heisenberg chain model have been investigated by means of the transfer matrix renormalization group (tmrg) method. considering different crystal structures, by changing the interactions among different spins and the external magnetic fields, we first investigate the magnetic susceptibility, magnetization, and specific heat of the distorted diamond chain as a model of ferrimagnetic spin systems. the susceptibility and the specific heat show different features for different ferromagnetic (f) and antiferromagnetic (af) interactions and different magnetic fields. a 1/3 magnetization plateau is observed at low temperature in a magnetization curve. then, we discuss the theoretical mechanism of the double-peak structure of the magnetic susceptibility and the three-peak structure of the specific heat of the compound cu-3(co3)(2)(oh)(2), on which an elegant measurement was performed by kikuchi [phys. rev. lett. 94, 227201 (2005)]. our computed results are consistent with the main characteristics of the experimental data. meanwhile, we find that the double-peak structure of susceptibility can be found in several different kinds of spin interactions in the diamond chain. moreover, a three-peak behavior is observed in the tmrg results of magnetic susceptibility. in addition, we perform calculations relevant for some experiments and explain the characteristics of these materials.
