Magnetic enhancement and coding in mechanosynthesized Ni{sub 0.3}Zn{sub 0.7}Fe{sub 2}O{sub 4} nanoparticles

The nanosized Ni{sub 0.3}Zn{sub 0.7}Fe{sub 2}O{sub 4} (∼ 15 nm) has been synthesized by high energy ball milling of the bulk powder sample. The sample has been characterized by powder x-ray diffraction, field emission and transmission electron microscopic and dc magnetic measurement techniques. The...

Description
Summary:The nanosized Ni{sub 0.3}Zn{sub 0.7}Fe{sub 2}O{sub 4} (∼ 15 nm) has been synthesized by high energy ball milling of the bulk powder sample. The sample has been characterized by powder x-ray diffraction, field emission and transmission electron microscopic and dc magnetic measurement techniques. The dc magnetic measurement on the sample indicates that the sample exhibit enhancement of magnetization compared to its counterparts synthesized by chemical methods. Moreover, the system stores the memory of either decrease or increase of magnetic field enabling a magnetic coding of “0” and “1” which can be profitably used in magnetic storage and sensing devices.
