Ofer Kfir,Patrik Grychtol,Emrah Turgut,Ronny Knut,Ronny Knut,Dmitriy Zusin,Dimitar Popmintchev,Tenio Popmintchev,Hans T. Nembach,Hans T. Nembach,Justin M. Shaw,Avner Fleischer,Henry C. Kapteyn,Margaret M. Murnane,Oren Cohen +14 more
TL;DR: In this article, the first bright, phase-matched, extreme ultraviolet circularly-polarized high harmonics source was demonstrated for magnetic circular dichroism measurements at the M-shell absorption edges of Co.
Journal ArticleDOI
Near-room-temperature colossal magnetodielectricity and multiglass properties in partially disordered La2NiMnO6
Debraj Choudhury,Pranab K. Mandal,Roland Mathieu,Abhijit Hazarika,S. Rajan,A. Sundaresan,Umesh V. Waghmare,Ronny Knut,Olof Karis,Per Nordblad,D. D. Sarma,D. D. Sarma,D. D. Sarma +12 more
TL;DR: This work establishes a unique way to obtain colossal magnetodielectricity, independent of any striction effects, by engineering the asymmetric hopping contribution to the dielectric constant via the tuning of the relative-spin orientations between neighboring magnetic ions in a transition-metal oxide system.
Non-collinear generation of angularly isolated circularly polarized high harmonics

Victoria A. Coleman,Ronny Knut,O. Karis,Helena Grennberg,Ulf Jansson,Ronald A. Quinlan,Brian C. Holloway,Biplab Sanyal,Olle Eriksson +8 more
TL;DR: In this article, a σ ∗ resonance at 287 eV in the carbon K-edge x-ray absorption spectra is observed with acid treatment and is assigned to C-O states.
Journal ArticleDOI
Electronic structure and chemical and magnetic interactions in ZnO doped with Co and Al : Experiments and ab initio density-functional calculations
Diana Iusan,Ronny Knut,Biplab Sanyal,Olof Karis,Olle Eriksson,Victoria A. Coleman,Gunnar Westin,J. Magnus Wikberg,Peter Svedlindh +8 more
TL;DR: In this article, the results of electronic structure and magnetization measurements of Co:ZnO and Co:znO codoped with Al thin-film samples fabricated by solution-based methods together with ab initio electro-magnetic measurements were presented.
