Erik Folven

About

Erik Folven is a full Professor at the Department of Electronic Systems. He is co-leading a research group where computer scientists and physicists work together towards new spin-based computational paradigms.

Folven is currently coordinating the EU FET-Open project, SpinENGINE, where NTNU together with researchers from leading European universities and IBM aim at a breakthrough in spin-based extreme low-power computing devices. He is also the project leader for the NRC funded project SPrINTER: Spin-based Intermittent Computer, where a radically new technology for batteryless intermittent computing devices required for a sustainable digital society is targeted.

Research Interests:

Artificial spin systems
Superferromagnetism
Computer modelling of nanomagnetic ensembles
Domain engineering in complex oxides
Magnetic domain imaging (X-PEEM, MFM, STXM, MOKE)
Nanofabrication (EBL, FIB, Ion-patterning)
