Abstract: The fate and scientific heritage of the outstanding scientist Alkey Khakanovich Margulan is always relevant. The phenomenon of Margulan remains as an example for all people who have dedicated their work to science. The article traces the chronicle of his life path (1904-1985). His parents raised him in a love for his native land, culture, history of the Kazakh people. He was an active, creative person, he communicated with prominent people, also he collaborated with editors of the republic magazine and newspapers. Among the scientific researches, includes the history of Kazakh epics, folklore heritage, oral folk art. In his scientific works, he describes the historical and topographical backgrounds of different places of Kazakhstan. He collected a lot of materials in fieldworks to present them for the next generations. main stages of his scientific activities as the head of the Central Kazakhstan Archaeological Expedition, his contribution to ethnography, philology and other areas of humanitarian science, scientific and public recognition of A. Kh. Margulan as a unique scientist who devoted himself to the study of the history and culture of Kazakhstan. A. Kh. Margulan showed himself as an archeologist, folklorist, literary critic, art historian, orientalist, ethnographer, historian, linguist, cultural studies expert. He was a qualified specialist in the study of ancient Kazakh history and culture.

Abstract: Many-body Green's function, and mean field theories have been developed for magnetic systems MgxNi1−xFe2O4. We apply this theory to evaluate thermal magnetization and magnetic susceptibility for different values of magnetic field and dilution x, by considering all components of the magnetisation when an external magnetic field is applied in (x-z)-plane. The critical temperatures of MgxNi1−xFe2O4 systems in the range 0 ≤ x ≤ 1 have been deduced. The Green's function results are compared with the results of high temperature series expansion technique, and experimental magnetic measurements.
