CoFe2O4 nano particles and CoFe2O4-rGO nano hybrids were synthesized via 1-hexanol assisted in situ reduction and growth process under solvothermal conditions for the first time and were characterized. Morphological and dimensional analysis showed spherical nano particles of average size 15-27 nm. Magneto dielectric spectroscopy revealed the formation of ultra low dielectric constant of 3.21 (@1 MHz) nano particles with negligible loss of as low as 0.03 (@3 GHz). Nano hybrid were also tailored to show electromagnetic absorption from 12 MHz to 3 GHz otherwise absent at this frequency.
