Nonlocal magnetization dynamics in ferromagnetic heterostructures
Two complementary effects modify the GHz magnetization dynamics of nanoscale heterostructures of ferromagnetic and normal materials relative to those of the isolated magnetic constituents. On the one
Enhanced gilbert damping in thin ferromagnetic films.
TLDR
The precession of the magnetization of a ferromagnet is shown to transfer spins into adjacent normal metal layers, slowing down the precession corresponding to an enhanced Gilbert damping constant in the Landau-Lifshitz equation.
Spin Hall magnetoresistance induced by a nonequilibrium proximity effect.
We report anisotropic magnetoresistance in Pt|Y(3)Fe(5)O(12) bilayers. In spite of Y(3)Fe(5)O(12) being a very good electrical insulator, the resistance of the Pt layer reflects its magnetization
Spin pumping and magnetization dynamics in metallic multilayers
We study the magnetization dynamics in thin ferromagnetic films and small ferromagnetic particles in contact with paramagnetic conductors. A moving magnetization vector causes ‘‘pumping’’ of spins
Theory of spin Hall magnetoresistance
We present a theory of the spin Hall magnetoresistance (SMR) in multilayers made from an insulating ferromagnet F, such as yttrium iron garnet (YIG), and a normal metal N with spin-orbit
Detection and quantification of inverse spin Hall effect from spin pumping in permalloy/normal metal bilayers
Spin pumping is a mechanism that generates spin currents from ferromagnetic resonance over macroscopic interfacial areas, thereby enabling sensitive detection of the inverse spin Hall effect that
Spin Seebeck insulator.
TLDR
It is revealed that, despite the absence of conduction electrons, the magnetic insulator LaY(2)Fe(5)O(12) can convert a heat flow into a spin voltage, which can be converted into an electric voltage as a result of the inverse spin Hall effect.
Spin caloritronics.
TLDR
An overview of the understanding and the experimental state-of-the-art concerning the coupling of spin, charge and heat currents in magnetic thin films and nanostructures is given.
Quantifying spin Hall angles from spin pumping: experiments and theory.
TLDR
It is shown how spin Hall effects can be quantified by integrating Ni{80}Fe{20}|normal metal (N) bilayers into a coplanar waveguide and developed a theory that accounts for both.
