“Spintronics: from hard disk drives to magnetic hedgehogs”
Semiconductor-based electronic devices rely on the flow of charge to store and process information. Spintronics, short for spin electronics, aims to utilise the spin degree of freedom in addition to the electron’s charge, promising much faster processing speeds, lower power consumption, and novel functionality. The most well-known application of spintronics is in the form of hard disk drives, recognized through the 2007 Nobel prize to Albert Fert and Peter Grünberg for the discovery of giant magneto-resistance. In this talk I will give a brief overview of spintronics and its applications, touching on very recent developments in the field of skyrmionics, where nano-metric sized topologically protected objects hold the promise for a new class of novel spintronics devices.
