Design & Fabrication of an Experimental Set-up for Susceptibility Measurement

Sharma, Rakhee (2011) Design & Fabrication of an Experimental Set-up for Susceptibility Measurement. MSc thesis.



In this project , an experimental set up for ac susceptibility measurement, is designed and fabricated . The setup comprises of, primary coil, secondary coil and sample holder. The basic principle of the setup is “mutual induction”. Copper wire winding is done over secondary and primary coil uniformly. When current passed, the coil gets magnetised which in turn magnetizes the sample. The setup is fabricated both for room temperature and high temperature susceptibility measurement. A sample is prepared whose susceptibility is to be measured. Cobalt Ferrite, a ferrimagnetic sample is chosen for the purpose. The sample is made by auto combustion sol-gel method. XRD characterization was carried out. Measurements were taken at high temperature and susceptibility versus temperature graphs were plotted. The graphs are in good agreement with the standard CFO graphs.
