Abstract
Being a part of a globalized society, we are using data at a truly unprecedented rate. Given the daily rise in the need for data and space consumption, it is clear that technology must be developed that will not only conserve space but also expand memory. Storage capacity is a key factor in the development of portable devices such as mobile, MP3 players, digital cameras, etc. In today's technology data storage capacity is crossing over its limit due to the superparamagnetic effect. This technology with longitudinal recording has an estimated limit of 100-200 gigabytes/sq.inch whereas, by perpendicular recording, it increases almost 100 times. This study involves analyzing magnetic single domain nanoparticles suitable for the purpose of high density magnetic data storage. In this work, Co13Cu87 and Fe3O4 have been studied and are speculated to perform satisfying performances. It has been shown that the magnetic characteristics of these nanoalloys can be easily tailored, making it versatile and scalable for storing data.
