Spontaneous Electric Polarization in Graphene Polytypes
Simon Salleh Atri, Wei Cao, Bar Alon +8
A crystalline solid is a periodic sequence of identical cells, each containing one or more atoms. If the constituting unit cell is not centrosymmetric, charge may distribute uneven…
Cumulative Polarization Coexisting with Conductivity at Interfacial Ferroelectrics
Swarup Deb, Wei Cao, Noam Raab +7
Ferroelectricity in atomically thin bilayer structures has been recently predicted1 and measured[2-4] in two-dimensional (2D) materials with hexagonal non-centrosymmetric unit-cell…
Giant spin transfer torque in atomically thin magnetic bilayers
Weihao Cao, Matisse Wei-Yuan Tu, Jiang Xiao +1
In cavity quantum electrodynamics, the multiple reflections of a photon between two mirrors defining a cavity is exploited to enhance the light-coupling of an intra-cavity atom. We…
Coherent spin pumping in a strongly coupled magnon-magnon hybrid system
Yi Li, Wei Cao, Vivek P. Amin +10
We experimentally identify coherent spin pumping in the magnon-magnon hybrid modes of permalloy/yttrium iron garnet (Py/YIG) bilayers. Using broadband ferromagnetic resonance, an "…
Measurement of spin mixing conductance in NiFe/-W and NiFe/-W heterostrucutures via ferromagnetic resonance
W. Cao, J. Liu, A. Zangiabadi +2
We present measurements of interfacial Gilbert damping due to the spin pumping effect in NiFe/W heterostructures. Measurements were compared for heterostructures in w…
Nearly isotropic spin-pumping related Gilbert damping in Pt/NiFe/Pt
W. Cao, L. Yang, S. Auffret +1
A recent theory by Chen and Zhang [Phys. Rev. Lett. 114, 126602 (2015)] predicts strongly anisotropic damping due to interfacial spin-orbit coupling in ultrathin magnetic films. In…
Characterization of spin relaxation anisotropy in Co using spin pumping
Yi Li, Wei Cao, William E. Bailey
Ferromagnets are believed to exhibit strongly anisotropic spin relaxation, with relaxation lengths for spin longitudinal to magnetization significantly longer than those for spin t…
Phase-resolved imaging of edge-mode spin waves using scanning transmission x-ray microscopy
Cheng Cheng, William E. Bailey
We have imaged the excitation of small-amplitude spin-wave eigenmodes, localized within 100 nm of the vertices of nanoscale NiFe ellipses, using time-resolved…
