Mn Katkılı PIN-PMN-PT Tekil Kristalinin Dielektrik Katsayısı, Relaksiyon Zamanı ve Aktivasyon Enerjisinin Hesaplanması

Relaksör-ferroelektrik malzemeler 1950 li yıllarda keşfedilmiştir, birçok uygulamada kullanılmasınarağmen hala bazı mekanik ve elektrik özellikleri tam olarak anlaşılamamıştır. Özellikle ferroelektrik fazgeçişlerindeki, mekanik ve elektriksel davranımlarının sıcaklık bağımlılıklarını tam olarak modelleyebilenbir yaklaşım eksikliği vardır. Bu çalışmada, Landau fenomonolojik teori kullanılarak, Mn katkılı PIN-PMNPT tek kristal karışım malzemenin ferroelektrik rhombohedral-monoklinik faz geçişinde (TC=112 0C) 512ve 584 cm-1 Raman modları için; kendiliğinden polarizasyon, dielektrik duyarlık ve gevşeme zamanısıcaklığa bağlı olarak hesaplanmıştır. Landau fenomonolojik teoriden türetilen dielektrik duyarlıkbağıntısı, deneysel veriler ile uyumlu sonuçlar vermiştir. Ayrıca, ferroelektrik rhombohedral fazda farklısıcaklık aralıkları için aktivasyon enerjileri pseuode-spin fonon ve enerji dalgalanma model yaklaşımlarıkullanılarak hesaplanmıştır. Her iki model kullanılarak hesaplanan sönümleme sabiti değerlerimiz,gözlemlenen verilerle uyumlu çıkmıştır.

Calculation of Dielectric Coefficient, Relaxation Time and Activation Energy of Mn Compounded PIN-PMN-PT Mono Crystal

Relaxor-ferroelectric materials were discovered in the 1950s, and although they are used in many applications, some of their mechanical and electric properties have not fully understood yet. There haven't been an adequate approach that can precisely model the temperature dependencies of their mechanical and electrical behaviour, especially in ferroelectric phase transitions yet. In this study, using Landau phenomenological theory, Mn-doped PIN-PMN-PT single crystal mixture material ferroelectric rhombohedral-monoclinic phase transition (TC=112 0C) for 512 and 584 cm-1 Raman modes; spontaneous polarization, dielectric sensitivity and relaxation time were calculated based on temperature. The dielectric precision correlation derived from Landau phenomenological theory yielded results consistent with experimental data. Furthermore, activation energies for different temperature ranges in the ferroelectric rhombohedral phase were calculated using pseudospin Phonon and energy fluctuation model approaches. Our damping constant values, which were calculated using both models, were good well consistent with the observed data.
