Transfer Matris Yöntemi Kullanılarak Spin 5/2 Ising Zincirinin Manyetik Özelliklerinin İncelenmesi

Manyetik alan altındaki bir boyutlu spin 5/2 Ising modelinin manyetik özellikleri transfer matris metodu kullanılarak incelenmiştir. Termodinamik cevap fonksiyonları ölçeklendirilmiş sıcaklık ve manyetik alanın farklı değerleri için elde edilmiştir. Helmholtz serbest enerjisinin sıcacklığa bağlı değişiminden yararlanarak, sistemin entropi ve ısı kapasitesi hesaplanmıştır. Similasyon sonuçları, manyetik alan şiddetinin artmasıyla ısı kapasitesinin bağıl olarak daha yüksek sıcaklık bölgesine kaydığını göstermektedir ve bu bulgular düşük spin değerli bir boyutlu Ising sistemleri için elde edilen daha önceki sonuçlar ile uyumludur.

Investigation of Magnetic Properties of Spin 5/2 Ising Chain by Using Transfer Matrix Method

A magnetic property of the one dimensional spin 5/2 Ising model under the magnetic field has been investigated by means of transfer matrix method. Thermodynamic response functions are also obtained for varying values of scaling temperature and scaling magnetic field. Entropy and heat capacity of the system were calculated by benefiting from the temperature dependencies of Helmholtz free energy. Our simulation results demonstrate that as the strength of the magnetic field is increased, heat capacity tend to shift to the relatively higher temperature regions, and these findings are consistent with previous results for the low spin values in one dimensional Ising systems.
