"ABSTRAKModel dinamis Landau Khalatnikov di gunakan untuk mempelajari energi bebas Gibbsdan kurva histeresis lapisan tipis Barium Zirkonium Titanat (BZT) dengan doping Lantanum danIndium. Model statis Landau Devonshire juga di pelajari dengan bahan yang sama. Hasil modeldigambarkan dan dianalisis menggunakan pogram Delphi 6 buatan mandiri yang dijalankan padaWindows. Kedua hasil model dibandingkan dengan kurva hasil eksperimen yang diukurmenggunakan rangkaian Sawyer-Tower. Hasil kesesuaian model dan eksperimen di tunjukanoleh R-Weighted Pattern (Rwp), yang merupakan perhitungan satistik untuk menunjukankesalahan. Beberapa parameter seperti frekuensi, amplitudo medan listrik dan faktor skaladivariasikan untuk merubah model secara halus. Hasil menunjukan nilai Rwp kurang dari 10%menunjukan model cukup memuaskan.

ABSTRACTDynamic Landau Khalatnikov model is utilized to study Gibbs free energy and hysteresiscurves of Barium Zirconium Titanate (BZT) thin films doped by Lanthanum and Indium. Thestatic Landau-Devonshire was also explored for the same cases. The model is plotted andanalysed using home made Delphi 6 program running on Windows platform. Both model is thecompared with the experimental hysteresis curves which were measured by using Sawyer-Towercircuit. The matching of the model and experiment is indicated by R-Weighted Pattern (Rwp),which is a statistical number to indicate the discrepancy. By varying the adjustable parameterssuch as frequency, energy amplitude and scale factor to model was slowly modified. The resultsshowed that Rwp was less than 10% that indicates the model is satisfactory."

"The book is an expanded autobiography of the famous theoretical physicist Isaak Khalatnikov. He worked together with L.D. Landau at the Institute for Physical Problems lead by P.L. Kapitza. He is the co-author of L.D. Landau in a number of important works. They worked together in the frame of the so-called Nuclear Bomb Project. After the death of L.D. Landau, I.M. Khalatnikov initiated the establishment of the Institute for Theoretical Physics, named in honour of L.D. Landau, within the USSR Academy of Sciences. He headed this institute from the beginning as its Director. The institute inherited almost all traditions of the Landau scientific school and played a prominent role in the development of theoretical physics. So, this is a story about how the institute was created, how it worked, and about the life of the physicists in the "golden age" of the Soviet science. A separate chapter is devoted to today´s life of the institute and the young generation of physicists working now in science."
