Duisburg-Essen and Helmholtz-Zentrum Berlin explain why thin iron demagnetises faster
Researchers at the University of Duisburg-Essen and Helmholtz-Zentrum Berlin report that magnetic order at material interfaces explains why thinner iron layers are more easily demagnetised by laser pulses.
Why it matters: Research groups working on magnetic data storage have a new published explanation, from Duisburg-Essen and Helmholtz-Zentrum Berlin, of laser-driven demagnetisation in thin iron layers.
According to the announcement, the thinner an iron layer is, the more easily a laser pulse can demagnetise it.
Researchers from the University of Duisburg-Essen, working with Helmholtz-Zentrum Berlin and other partners, say the decisive factor is the magnetic order at the material's interfaces.
The team said the findings could in the long term help develop new technologies for magnetic data storage.
The results were published in the journal Advanced Science.

Groups working on magnetic data storage now have a published account, in Advanced Science, from Duisburg-Essen and its partners. It attributes the easier laser demagnetisation of thinner iron layers to magnetic order at the interfaces.
