Higgs and Goldstone spin-wave modes in striped magnetic texture
Matías Grassi, Moritz Geilen, Kosseila Ait Oukaci +6
Spontaneous symmetry breaking is ubiquitous in physics. Its spectroscopic signature consists in the softening of a specific mode upon approaching the transition from the high symme…
Electrical spectroscopy of forward volume spin waves in perpendicularly magnetized materials
M. Sushruth, M. Grassi, K. Ait-Oukaci +8
We study the potential of all-electrical inductive techniques for the spectroscopy of propagating forward volume spin waves. We develop a one-dimensional model to account for the e…
Unidirectional spin-wave channeling along magnetic domain walls of Bloch type
Yves Henry, Daniel Stoeffler, Joo-Von Kim +1
From the pioneering work of Winter [Phys. Rev. 124, 452 (1961)], a magnetic domain wall of Bloch type is known to host a special wall-bound spin-wave mode, which corresponds to spi…
Conductance oscillations in graphene/nanoclusters hybrid material: towards large area single electron devices
Florian Godel, Louis Donald Notemgnou Mouafo, Guillaume Froehlicher +5
Large assemblies of self-organized aluminum nanoclusters embedded in an oxide layer are formed on graphene templates and used to build tunnel-junction devices. Unexpectedly, single…
Propagating spin-wave normal modes: A dynamic matrix approach using plane-wave demagnetizating tensors
Yves Henry, Olga Gladii, Matthieu Bailleul
We present a finite-difference micromagnetic approach for determining the normal modes of spin-waves propagating in extended magnetic films and strips, which is based on the linear…
Voltage-controlled inversion of tunnel magnetoresistance in epitaxial Nickel/Graphene/MgO/Cobalt junctions
F. Godel, M. Venkata Kamalakar, B. Doudin +3
We report on the fabrication and characterization of vertical spin-valve structures using a thick epitaxial MgO barrier as spacer layer and a graphene-passivated Ni film as bottom…
