Journal ArticleDOI
Ultrafast magneto-optics in nickel: magnetism or optics?
TL;DR: This work achieved a first complete identification by explicitly measuring the time-resolved Kerr ellipticity and rotation, as well as its temperature and magnetic field dependence in epitaxially grown Cu/Ni/Cu wedges.
Journal ArticleDOI
All-optical probe of coherent spin waves.
van M Maarten Kampen,C Csaba Jozsa,JT Jürgen Kohlhepp,Patrick LeClair,Liesbet Lagae,de Wjm Wim Jonge,B Bert Koopmans +6 more
TL;DR: Recording the temporal evolution of the precessing spins by a time-delayed probe-pulse provides a quantitative method to study locally the magnetic anisotropy, as well as switching and damping phenomena in micromagnetic structures.
Journal ArticleDOI
Field-free magnetization reversal by spin-Hall effect and exchange bias.
van den A Arno Brink,G Guus Vermijs,Amp Aurelie Solignac,Amp Aurelie Solignac,J Jungwoo Koo,JT Jürgen Kohlhepp,Hjm Henk Swagten,B Bert Koopmans +7 more
TL;DR: An in-plane exchange bias is created and shown to enable field-free S HE-driven magnetization reversal of a perpendicularly magnetized Pt/Co/IrMn structure.
Journal ArticleDOI
Large magnetoresistance using hybrid spin filter devices
TL;DR: In this paper, a magnetic spin filter is used to create a magnetoresistive tunnel device, somewhat analogous to an optical polarizer analyzer configuration, which yields a previously unobserved magnetoresistance effect, exceeding 100%.

Large magnetoresistance using hybrid spin filter devices

TL;DR: In this paper, a magnetic "spin filter" tunnel barrier, sandwiched between a non-magnetic metal and a magnetic metal, is used to create a new magnetoresistive tunnel device, somewhat analogous to an optical polarizer-analyzer configuration.
