Electrical spin manipulation in graphene nanostructures
R. Ortiz, N. A. García-Martínez, J. L. Lado +1
We propose a mechanism to drive singlet-triplet spin transitions electrically, in a wide class of graphene nanostructures that present pairs of in-gap zero modes, localized at oppo…
Engineering the eigenstates of coupled spin-1/2 atoms on a surface
Kai Yang, Yujeong Bae, William Paul +8
Quantum spin networks having engineered geometries and interactions are eagerly pursued for quantum simulation and access to emergent quantum phenomena such as spin liquids. Spin-1…
Faster, farther, stronger: spin transfer torque driven high order propagating spin waves in nano-contact magnetic tunnel junctions
A. Houshang, R. Khymyn, M. Dvornik +6
Short wave-length exchange-dominated propagating spin waves will enable magnonic devices to operate at higher frequencies and higher data transmission rates.1 While GMR based magne…
Multiphase mean curvature flows with high mobility contrasts: a phase-field approach, with applications to nanowires
Elie Bretin, Alexandre Danescu, José Penuelas +1
The structure of many multiphase systems is governed by an energy that penalizes the area of interfaces between phases weighted by surface tension coefficients. However, interface…
Laser induced THz emission from femtosecond photocurrents in Co/ZnO/Pt and Co/Cu/Pt multilayers
G. Li, R. V. Mikhaylovskiy, K. A. Grishunin +3
The ultrashort laser excitation of Co/Pt magnetic heterostructures can effectively generate spin and charge currents at the interfaces between magnetic and nonmagnetic layers. The…
Characterization of highly crystalline lead iodide nanosheets prepared by room-temperature solution processing
Riccardo Frisenda, Joshua O. Island, Jose L. Lado +15
Two-dimensional semiconducting materials are particularly appealing for many applications. Although theory predicts a large number of two-dimensional materials, experimentally only…
