Nanocrystalline CuFe1.9La0.1O4 powder was prepared by the citrate precursor method. The magnetic properties of the sample were measured by using a vibration sample magnetometer (VSM), which showed that the sample exhibited a typical ferrimagnetic behavior at room temperature.

Abstract: “[What is needed] is the scientific approach, the adventurous and yet critical temper of science, the search for truth and new knowledge, the refusal to accept anything without testing and trial,” —Jawaharlal Nehru. Now in this age of Information technology a vast area is covered for Image designing using Computer graphics. Computer graphics generally means Creation, storage, manipulation of Images using Geometric Transformations. The Changes rapidly done in the field of computer graphics have made representation of real world images possible. In this paper we propose to introduce some key ideas in computer graphics using principles of mathematics.
