After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Theoretical analysis of structural and magnetic behavior of Ce doped nickel ferrite nanoparticles

    Ferrites are magnetic materials having spinel structure. They are important because of their magnetic properties which make them applicable in various fields. Properties of ferrites depend upon the synthesis method, temperature, cation distribution, doping with different metal ions etc. In the present work, theoretical analysis of various structural and magnetic properties of Ce doped nickel ferrite nanoparticles NiCeyFe2-yO4 (Ce concentration y =0.01 to 0.08) has been done. Experimental data of X-Ray Diffraction, Mössbauer Spectroscopy and VSM has been taken from literature for structural analysis, cation distribution and saturation magnetization respectively. Ce ions being larger in size are assumed to occupy the octahedral sites. Different structural parameters like bond lengths, bond angles, site radii etc. were calculated assuming that all Ce ions are entering into the spinel lattice with increasing concentration. The calculated values show matching with experimental values only up to the 0.01 concentration of Ce. So it was concluded that Ce ions are not entering into the spinel lattice after the concentration of 0.01 but are moving toward grain boundaries. The cation distribution was again refined and structural and magnetic parameters were calculated which now show almost similar trend as the experimental values for all samples. Both theoretically and experimentally it was found that doping with Ce reduces the magnetization of nickel ferrite however there is difference between the calculated and experimentally observed values. Inclusion of some additional factors such as magnetic moment due to orbital motion and spin canting may give the possibility of getting same calculated values. This opens a scope for further experimental study of Ce doped ferrite samples.
