We report an unusual consequence of magnetic memory effect in nanostructures, which is prepared using an electrochemical route. Chemical phases of nanostructures are characterized by X-ray diffraction, optical, and Mössbauer spectroscopic studies. The static and dynamic aspects of dc magnetization studies are carried out. Thermal variation of zero-field-cooled (ZFC) magnetization displays a signature of blocking temperature at 215 K. Another broadened peak is also evident in the field-cooled (FC) magnetization at 40 K . Signature of memory effect is observed below TG after cooling the sample both in ZFC and FC protocols. Appearance of memory effect in the ZFC protocol confirms spin-glass-like state below . Interestingly, memory effect is absent below even in FC protocol, although a large particle size distribution is noticed in the nanostructures. The results address the fundamental question whether substantial particle size distribution is sufficient enough for the memory effect in the FC protocol as found in the literatures.
