Abstract:
<p> Collective magnetic behavior in nanostructures is a phenomenon commonly observed in various magnetic systems. It arises due to competing inter/intra&ndashparticle; interactions and size distribution and can manifest in phenomena like magnetic freezing, magnetic aging, and exchange bias (EB) effect. In order to probe these rather complex phenomena, conventional DC and AC magnetic measurements have been performed along with radio&ndashfrequency; transverse susceptibility (TS) measurements.

Ferrihydrite is a natural iron hydroxide occurring mostly in surface waters.

Abstract:
<p> Ferromagnetic nanostructures are under considerable interest for producing larger capacity magnetic storage devices. Denser magnetic storage leads to finer magnetic grains and smaller bit size, however, as bit size shrinks it approaches a limit, such that, a single magnetic grain is only capable of holding a single bit of information. Therefore, changes in nanoscale morphology can produce different magnetic properties, so characterizing nanostructures is crucial. Atomic force microscopy (AFM) is a common way to model the morphology of ferromagnetic thin films atop of nanosphere templates.

Abstract:
Nanomagnetic devices have been projected as an alternative to transistor-based switching devices due to their non-volatility and potentially superior energy-efficiency. The energy efficiency is enhanced by the use of straintronics which involves the application of a voltage to a piezoelectric layer to generate a strain which is ultimately transferred to an elastically coupled magnetostrictive nanomaget, causing magnetization rotation. The low energy dissipation and non-volatility characteristics make straintronic nanomagnets very attractive for both Boolean and non-Boolean computing applicatio
