▎ 摘  要

The performance of graphene for specific applications is inevitably reliable to the challenge and prospect of various defects during the production process causing disorder. A finite cluster approximation has been directed to study separately two kinds of disorder including (i) bond dilution and (ii) bond randomness described by random variables p and Delta, respectively, for mixed spin-3/2 and spin-1/2 trilayer graphene-like structure. The dependence of the critical and compensation temperature of the concentration p and the fluctuation Delta and various exchange parameters has been discussed. In particular, we have found that the present system can display a horizontal reentrance because of the competition of the exchange couplings strength with the bond concentration p disfavoring the ferrimagnetic order. Interestingly, two compensation points behavior may appear in a certain range of crystal field. Finally, all these behavior has been validated by analyzing the total, sigma- and S- sublattice magnetizations.
