Graphene Exhibits Magnetism - University of Manchester Research

Do you have Magnetic personality? Well, Graphene has. The material which attracts many scientists is now going to attract iron! Scientists researching on the properties of Graphene have now revealed that Graphene exhibits magnetism. Graphene however obtains this property by the virtue of other non-magnetic materials.

The project team consists of Dr Irina Grigorieva and Professor Sir Andre Geim, both of The University of Manchester. Interestingly, Professor Geim was one of the members of research group who pioneered Graphene and received Nobel Prize for the same. In the present research, scientists experimented with Chicken wire. In this wire, efforts were done to remove defects, if any. It was found that, lesser the number of defects, the more was Magnetic property. The defects were removed by filling the vacancies in atoms of chicken wire by adding other non-magnetic atoms like Fluorine and removing atoms with vacancies i.e., Carbon.

Magnetism thus found by the team, is an important step to boost further #-Link-Snipped-#. However, even if you happen to magnetize this material to its fullest extent, it falls short in strength of normal magnets. In other words, presently, even the most magnetized Graphene cannot stick to Fridge or other iron articles.

Hence strengthening the magnetic properties of this wonder material remains a tough task ahead of scientists. However, the little magnetic field that Graphene generates, can be crucial for many applications. The property can be particularly useful in Spintronics devices. Simply stating, the magnetic phenomenon can be best utilized in your computer hard disc which couples electric current and magnetism to run.

Graphene is fast proving itself as a wonder material for scientists. Since its discovery, it has fast become a subject of research all over the world. Developing #-Link-Snipped-#, its use in #-Link-Snipped-#, its rise as an alternative for #-Link-Snipped-# are just a few aspects of Graphene's ever growing importance. Another attribute 'Magnetism' added to the material will increase its demand in technological scenario further.
