Abstract
We present a dielectric study on ferrofluid solutions of Fe2CoO4 in di ethylene glycol or dibutyl phthalate, from 50 mHz to 10 MHz, in the te mperature range -160-+40-degrees-C. When a transversal magnetic field is applied, a magnetodielectric anisotropy is in evidence. Above a con centration limit the colloidal suspensions do not remain well disperse d at low temperature. Moreover it seems that the melting point of a so lution could be affected.
