dc.description.abstractÖZET Transfer matris metodu, bilineer (J) ve bikuadratik (K) değişim etkileşme Harmltoniyenine sahip spin-1 Ising modeline magnetik alan yokluğunda uygulandı. Spin- 1 Ising modelinin moleküler alan yaklaşımıyla incelenmesine alternatif olarak, transfer matris metodu ele alındı. Transfer matris metodunda düzen parametresi olan kuadrupol moment (Q) sıcaklığın fonksiyonu olarak bulundu. Bunun sonucu olarak; Q' nun kararlı çözümleri elde edilip, faz geçişleri belirlendi. Anizotropinin (- ) değişimine bağlı olarak kuadrupol moment Q' nun K. sıcaklığa bağlı olarak değiştiği görüldü. Transfer matris metoduyla elde edilen kuadrupol düzen parametresinin sıcaklığa bağlı kararlı çözümlerinin, moleküler alan yaklaşımıyla elde edilen kararlı çözümlerle uygunluğu belirlendi.
dc.description.abstractABSTRACT The transfer matrix method has been applied to spin-1 Ising model having Hamiltonian with bilinear (J) and biquadratic (K) variation interaction in the absence of magnetic field. Transfer matrix method has been considered as an alternative to examining of Ising model with molecular field approximation. The quadrupol moment (Q) being order parameter in the transfer matrix method has been found to be the function of temperature. As a result, stable solutions of Q have been obtained and phase transitions have been determined. The quadropol moment Q have been observed to change with respect to temperature in accordance with the variation of anisotropy ( - ). Temperature dependent stable solutions of quadrupol order parameter obtained K by transfer matrix method has been determined to agree with stable solutions obtained by molecular field approximation.en_US
