Abstract

Nanoparticles NiFe_2-xCe_xO₄ (x=0, 0.03, 0.06, 0.09, 0.12) was prepared by solgel combution method. The samples were characterized with VSM and Electrical measurements. Magnetic studies by Vibrating Sample Magnetometer (VSM) shows that magnetization (Ms) decreases with increase in Ce3+ concentration. Coercivity (Hc) first decreases for x=0.03, after which it increases up to x=0.12. Resistivity value increases as the x value increases.

Abstract

Raman and FT-IR absorption spectra of t-butyl alcohol and n-butyl alcohol pure components have been recorded in the liquid state in the region of 400-4000 cm ^-1. The data obtained have been used to propose complete vibrational assignments for each of the liquid component and the structural features are discussed. The variations in frequency shifts, intensities and line widths are discussed with a view to understanding the origin of such variations.
