M0.25Fe0.25Zn0.5Fe2O4 (M=Fe+2 ,Cu+2 ,Mn+2 ,Ni+2 & Co+2) nanoparticles (less than 10 nm in diameter) were produced by lowtemperature solid-state reaction (LTSSR) method. The structural properties of the produced nanoparticles were investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Also, their magnetic properties were assessed by alternating gradient-force magnetometer (AGFM). The superparamagnetic property was proved for all samples because of the absence of remanent magnetization. Moreover, the effect of M on the magnetic properties of M0.25Fe0.25Zn0.5Fe2O4 was studied and it was found that the maximum magnetization occurred for M= Co+2 (Co0.25 Fe0.25Zn0.5Fe2O4) where the minimum in related to Cu+2 (Cu0.25 Fe0.25Zn0.5Fe2O4)..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
