Nonlocal magnetization dynamics in ferromagnetic hybrid nanostructures
Two complementary effects modify the GHz magnetization dynamics of nanoscale hybrid structures of ferromagnetic and normal materials from those of the isolated magnetic constituents: On the one hand, a time-dependent ferromagnetic magnetization pumps a spin angular-momentum flow into adjacent materials and, on the other hand, spin angular momentum is transferred between ferromagnets by an appli...
متن کاملMagnetization Dynamics Symmetry in Spin Torque Induced Magnetization Switching
Magnetization dynamics symmetry plays important roles in magnetization switching. Here we study magnetic field and spin torque induced magnetization switching. Spin moment transferring from polarized itinerant electrons to local magnetization provides a magnetization switching mechanism without using external magnetic field. Besides its importance in fundamental magnetization switching dynamics...
متن کاملUltrafast magnetization dynamics in ferromagnetic materials
In recent magneto optical experiments (TR-MOKE) the timescale of laser induced demagnetization was found to be shorter than 0.5 ps. However, doubts have been raised if the measured signal reflects genuine loss of magnetic moment at all. Also, for these experiments no broadly accepted theory exists. Although a few models are able to fit the data, they generally have in common that they violate o...

متن کاملMagnetization switching in small ferromagnetic particles: Nucleation and coherent rotation
The mechanisms of thermally activated magnetization switching in small ferromagnetic particles driven by an external magnetic field are investigated. For low uniaxial anisotropy the spins rotate coherently while for sufficiently large uniaxial anisotropy they behave Ising-like, i.e., the switching then is due to nucleation. The crossover from coherent rotation to nucleation is studied for the c...
