Modelling of the size effect's influence on the critical temperature of the nanowires' phase transition
[摘要] Influence of the size effect on the magnetic phase transition's temperature and magnetic moment of the nanowires was modelled based on "average spin" method. As it was shown that Curie temperature was increased with nanowires' sizes increase. The calculated value of the critical exponent of the spin-spin correlations v = 0.737 is close to experimental value.
