Abstract
Thermomagnetic properties of fine CoFeO4 particles with average sizes of 43 , 51, 66. 195 and 465 Angstrom were investigated between 5 and 800 K in fie lds up to 140 kOe. The particles with sizes of 43 and 51 Angstrom behave su perparamagnetically at room temperature, but the others exhibit mixed super paramagnetic and ferrimagnetic behavior. The concentration of the ferrimagn etic phases and their magnetic properties were evaluated. (C) 1999 Elsevier Science B.V. All rights reserved.
