Project on the BRFFR "Influence of anion and cation nonstoichiometry on thermodynamic properties of solid solutions of perovskites"

Scientific research (R&D) of SSPA "Scientific-Practical Materials Research Centre of NAS of Belarus" and Belarusian State University of power of attorney № 0101/1688 of 05/11/2011, pursuant to the agreement with BRFFR number F12OB-047. Research on the topic "Influence of anion and cation nonstoichiometry on thermodynamic properties of solid solutions of perovskites".

The initial term of the research work on the subject of the contract - July 1, 2012, deadline for the job - June 30, 2014

Project Objective: to determine the effect of point defects in cation and anion sublattices on thermodynamic characteristics and process parameters on phase transformations in solid Sr2-xBaxFeMoO6-δ.

The main scientific idea of ​​the project is that the magnetization, magnetic phase transitions and magnetoresistance can be controlled by varying the concentration and ordering of cation and anion defects in perovskites. Using a low-temperature adiabatic calorimetry will provide accurate and reliable information on the phase transformation and cation ordering in complex metal oxide systems.

Scientific and practical groundwork: the Department of Physical Chemistry BSU have already accumulated many years of experience and has a team of researchers in the field of physical chemistry and thermodynamics of organic compounds. Conducted theoretical and experimental studies of and compliance with international standards in the field of thermochemical studies. Over the past years the staff published in various scientific journals (Journal of Chemical Thermodynamics, Journal of Chemical & Engineering Data, Vestsi NAS of Belarus, Thermochimica Acta). Experimental and human resource base can successfully implement the planned research. For the task will use a modern method of low-temperature adiabatic calorimetry.
