Abstract
In this study the design and set up of a very sensitive RF susceptometer based on a Robinson NMR oscillator is presented. This home-made susceptometer operates in a frequency range of 10-40 MHz and was successfully used to study thermal relaxation and particle interaction in magnetic nanoparticulated systems. Using this system we found the peak frequency associated to the energy absorption by the magnetite-based nanoparticulated material changing in the range of 17 to 28 MHz by applying a DC magnetic field up to 4 kOe. © 2010 American Institute of Physics.
