Studying at Cambridge


Dr Amalio Fernandez-Pacheco


Graduate degree (2005) and PhD (2009) in Physics at the University of Zaragoza, Spain. From 2010, postdoc at the group of Prof. Cowburn, first at Imperial College, and then at the Cavendish Laboratory-University of Cambridge, being a Marie Curie Fellow from 2010 to 2012. From 2014, EPSRC Early Career Fellow and Winton Advanced Research Fellow at the Cavendish Laboratory.

Research Interests

I am interested in studying novel ways to store and process binary information using magnetic nanostructures.

The Information Technology over the last few decades has been made possible due to the continuous downscaling of integrated circuits and storage devices. However, current high computing performance is accompanied with an exponential increase in power consumption, with serious implications for the environment. I investigate more efficient mechanisms to store information using Nanotechnology and magnetic materials. In particular, I am using advanced direct-write nanolithography techniques based on focused electron and ion beams to pattern magnetic materials at the nanoscale, aiming to create a new generation of spintronic devices.

The possibility to fabricate magnetic nanostructures using advanced maskless nanopatterning methods has a great potential in many Nanotechnology fields, including nanoelectronics, nano-sensing, biomagnetism and medicine, which allows me to collaborate with a wide range of research groups around the world.
