Imaging spin-wave damping underneath metals using electron spins in diamond
Iacopo Bertelli, Brecht G. Simon, Tao Yu +4
Spin waves in magnetic insulators are low-damping signal carriers that could enable a new generation of spintronic devices. The excitation, control, and detection of spin waves by…
Magnetic resonance imaging of spin-wave transport and interference in a magnetic insulator
Iacopo Bertelli, Joris J. Carmiggelt, Tao Yu +6
Spin waves - the elementary excitations of magnetic materials - are prime candidate signal carriers for low dissipation information processing. Being able to image coherent spin-wa…
Tunable magnetic interactions in LaAlO3/SrTiO3 heterostructures by ionic liquid gating
Chunhai Yin, Kumar Prateek, Wouter Gelling +1
The gating effect achieved by an ionic liquid and its electric double layer allows for charge transfer which can be an order of magnitude larger than with conventional dielectrics.…
Tuning Rashba spin-orbit coupling at LaAlO3/SrTiO3 interfaces by band filling
Chunhai Yin, Patrick Seiler, Lucas M. K. Tang +4
The electric-field tunable Rashba spin-orbit coupling at the LaAlO3/SrTiO3 interface shows potential applications in spintronic devices. However, different gate dependence of the c…
New insights into the electron trapping mechanism in LaAlO_3 / SrTiO3 heterostructures
Chunhai Yin, Alexander E. M. Smink, Inge Leermakers +6
In LaAlO3/SrTiO3 heterostructures, a commonly observed but poorly understood phenomenon is that of electron trapping in back-gating experiments. In this work, by combining magnetot…
Controlling supercurrents and their spatial distribution in ferromagnets
Kaveh Lahabi, Morten Amundsen, Jabir Ali Ouassou +5
Spin-triplet Cooper pairs induced in ferromagnets form the centrepiece of the emerging field of superconducting spintronics [1,2]. Usually the focus of research is on the spin pola…
Emergence of the stripe-domain phase in patterned Permalloy films
S. Voltan, C. Cirillo, H. J. Snijders +5
The occurrence of stripe domains in ferromagnetic Permalloy (Py=FeNi) is a well known phenomenon which has been extensively observed and characterized. This peculiar…
Manganese valence and magnetotransport in ultrathin films of LaCaMnO
C. Beekman, J. Aarts, M. Porcu +1
We report a comparative study of the properties of very thin films of LaCaMnO grown epitaxially under strain on flat SrTiO (STO), lattice matched on NdGaO…
