Home > Press > Superparamagnetic Lead Nanopowder - A New Milestone: Indian researchers have explored the superparamagntism of lead nanopowder

Abstract:
Indian researchers (Theivasanthi and Alagar) have discovered the superparamagntism of lead nanopowder. The group, based at Centre for Research and Post Graduate Studies in Physics, Ayya Nadar Janaki Ammal College has crossed an another milestone in its research activities by exploring the new behavior of this metal nanopowder. It comments: "It is really amazing to us; to our best knowledge, this is the first demonstration of superparamagnetic nature of lead nanopowder (Pb); so far, lead metal has been known as a diamagnetic; this new exploration of new behavior has moved us one step forward and upward in our research".

Superparamagnetic Lead Nanopowder - A New Milestone: Indian researchers have explored the superparamagntism of lead nanopowder

Sivakasi, India | Posted on October 1st, 2013

In their earlier reports, the researchers have explained the synthesis procedures of this metal powder [Theivasanthi et al, hgoo.gl/bXphv ] and explore its semi-conducting properties [Theivasanthi et al, goo.gl/IyWXzq ]. In their current report, the superparamagnetic properties have been explained [Theivasanthi et al, goo.gl/dyg2H1].

If both semiconducting and superparamagnetism behaviours available in same material, it will provide a single platform for computation and data storage. It will integrate computer memory with data processing lead to new kind of computation, in future. Findings of this study suggest that the synthesized material is an efficient superparamagnetic material. It can be utilized for various applications like magnetic, Storage Devices, Medical & Biomedical and other applications like Research tools in materials physics, geology, biology, medicine etc. Hysteresis Curve image of spherical Pb Nanoparticles is in Fig.1. This work throws some light on and helps further research on nano-sized lead powder.

Generally nano-materials have behaviors different from their bulk material. Size and shape control many of the physical properties including magnetic properties of nanomaterials. The present research has been done, based on this fact and superparamagnetic properties of Pb nanopowder have been explored. Vibrating Sample Magnetometer (VSM) study of the material indicates sigmoid or S-like shape hysteresis, without any loop / squareness (SQR i.e. Mr/Ms of the sample is 0.03517). It does not exhibit coercivity (Hc) saturated magnetization (Ms) and remanent magnetization (Mr). The net magnetization in the absence of an external field is zero. These characters confirm superparamagnetic properties.

"Our data clearly indicates the superparamagnetic nature of Pb nanopowder," the researchers comment, adding: "Further research related to application oriented of this material like magnetic and solar cells is going on."
