Abstract: A Pulsed NMR Spectrometer for analysis of ferromagnetic materials has been developed.It is based on Spinecho theory and coherent receive principle.It can operate in the frequency range 25-80MHz with the output power 10w. With using the spectrometer,the FNR line, enhancement factor and spin-spin relaxation T2 of ferromagnetic materials may be obtained at any temperature from 77°K to 300°K.It can also be used to measure the broad NMR line of non magnetic materials.
