Nonlocal magnetization dynamics in ferromagnetic hybrid nanostructures

Linear and nonlinear magnetization dynamics in thin ferromagnetic films and nanostructures

Switching magnetization of a nanoscale ferromagnetic particle using nonlocal spin injection.

We have performed nonlocal spin injection into a nanoscale ferromagnetic particle configured in a lateral spin-valve structure to switch its magnetization only by spin current. The nonlocal spin injection aligns the magnetization of the particle parallel to the magnetization of the spin injector. The spin current responsible for switching is estimated from the experiment to be about 200 microA,...

Ultrafast magnetization dynamics of spintronic nanostructures.

The ultrafast (sub-nanosecond) magnetization dynamics of ferromagnetic thin films and elements that find application in spintronic devices is reviewed. The major advances in the understanding of magnetization dynamics in the two decades since the discovery of giant magnetoresistance and the prediction of spin-transfer torque are discussed, along with the plethora of new experimental techniques ...

Phase segregation dynamics for the Blume - Capel model with Kac interaction

We consider the Glauber and Kawasaki dynamics for the Blume-Capel spin model with weak long range interaction on the infinite lattice: a ferromagnetic ddimensional lattice system with the spin variable σ taking values in {−1, 0, 1} and pair Kac potential γJ(γ(|i − j|)), γ > 0, i, j ∈ ZZ . The Kawasaki dynamics conserves the empirical averages of σ and σ corresponding to local magnetization and ...
