Abstract
This paper presents modification for a model to express magnetic hysteresis loop and the calculation of hysteresis energy loss (HEL) for cobalt ferrite nanoparticles (CFNs) produced by modified citrate-gel method. A simulation of CFNs hysteretic loops was successfully carried out showing a good fitting between the calculated and experimental curve. In addition, HEL is predicted in an expression as a result of this modified model.
