Probing the flat-band limit of the superconducting proximity effect in Twisted Bilayer Graphene Josephson junctions
A. Diez-Carlon, J. Diez-Merida, P. Rout +13
While extensively studied in normal metals, semimetals and semiconductors, the superconducting (SC) proximity effect remains elusive in the emerging field of flat-band systems. In…
Watching Domains Grow: In-situ studies of polarization switching by combined Scanning Probe and Scanning Transmission Electron Microscopy
Hyejung Chang, Sergei V. Kalinin, Seungyeul Yang +9
Ferroelectric domain nucleation and growth in multiferroic BiFeO3 films is observed directly by applying a local electric field with a conductive tip inside a scanning transmission…
Near-field examination of perovskite-based superlenses and superlens-enhanced probe-object coupling
Susanne C. Kehr, Yongmin M. Liu, L. W. Martin +11
A planar slab of negative index material works as a superlens with sub-diffraction-limited imaging resolution, since propagating waves are focused and, moreover, evanescent waves a…
Interface ferromagnetism and orbital reconstruction in BiFeO3- La0.7Sr0.3MnO3 heterostructures
P. Yu, J. -S. Lee, S. Okamoto +14
We report the formation of a novel ferromagnetic state in the antiferromagnet BiFeO3 at the interface with La0.7Sr0.3MnO3. Using x-ray magnetic circular dichroism at Mn and Fe L2,3…
Spin-Charge-Lattice Coupling through Resonant Multi-Magnon Excitations in Multiferroic BiFeO3
M. O. Ramirez, A. Kumar, S. A. Denev +19
Spin-charge-lattice coupling mediated by multi-magnon processes is demonstrated in multiferroic BiFeO3. Experimental evidence of two and three magnons excitations as well as multim…
