There s a news that researchers at Dartmouth College found that Chromium displays different electrical properties while heating and cooling and these differences reflect restrained internal rearrangements of the electrons and thus in turns their spins.

As it is well known that most of the available antiferromagnets finds application in magnetic heads for reading data from a disc, chromium being an antiferromagnet can be a suitable candidate for these applications.

Scientists have long studied the electrical properties of ferromagnets and the influence of electron spin. Less attention has been paid, according to Soh and Kummamuru, to the influence of spin on the electrical properties in antiferromagnets;  where it is more difficult to manipulate and Chromium is special since it is the only simple element that is an antiferromagnet. The findings show that not only ferromagnets can be used in spintronics; there is a possibility that a...... [ Read the rest of this story ]
