Özet:

 The dynamic phase transition DPT temperatures and the dynamic phase diagrams are obtained for spin-12 Ising system under the presence of a time-dependent oscillating external magnetic field using the method that was purposed by Meijer and Edwards ANNALS of PHYSICS, 54, 240 1969 within the framework of the Bethe or constant coupling theory. The time variation of magnetization is investigated to find the phases in the system. Thermal behavior of the average magnetization is studied to characterize the nature continuous and discontinuous of transitions and to obtain the dynamic phase transition temperatures. The DPT temperatures are found always a second-order; hence there can be no tricritical point separating lines of first- and second-order dynamic phase transitions. This result agrees with the dynamic Monte-Carlo MC simulations of a two-dimensional kinetic spin-12 Ising model in an oscillating external magnetic field.

 Dinamik faz geçiş DPT sıcaklıkları ve dinamik faz diyagramları, Meijer ve Edwards ANNALS of PHYSICS, 54, 240 1969 tarafından Bethe veya sabit çiftlenim teorisi çerçevesinde amaçlanan yöntem kullanılarak, zaman bağımlı salınımlı dış manyetik alanın varlığında spin-12 Ising sistemi için elde edilir. Sistemdeki fazları bulmak için mıknatıslanmanın zamana göre değişimi incelenir. Ortalama mıknatıslanmanın termal davranışı, geçişlerin doğasını sürekli ve süreksiz karakterize etmek ve dinamik faz geçiş sıcaklıklarını elde etmek için incelenir. DPT sıcaklıkları her zaman ikinci dereceden bulunur; bu nedenle birinci ve ikinci dereceden dinamik faz geçişlerinin çizgilerini ayıran üçlü kritik nokta olamaz. Bu sonuç, salınımlı bir dış manyetik alanda iki boyutlu kinetik spin-12 Ising modelinin dinamik MC simülasyonlarıyla uyumludur.
