Nanoscale Confinement Enhances Ultrafast Demagnetization. [PDF]
Adv Sci (Weinh)Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...

Transverse Demagnetization Dynamics of a Unitary Fermi Gas [PDF]
Science, 2014 Untwisting the Spin Spiral Ultracold Fermi gases in the so-called unitary regime—where the diverging interactions between atoms make their thermodynamics universal—are an excellent test bed for an array of strongly interacting matter systems.

Structural dynamics during laser-induced ultrafast demagnetization [PDF]
Physical Review B, 2017 The mechanism underlying femtosecond laser pulse induced ultrafast magnetization dynamics remains elusive despite two decades of intense research on this phenomenon. Most experiments focused so far on characterizing magnetization and charge carrier dynamics, while first direct measurements of structural dynamics during ultrafast demagnetization were ...

Demagnetization dynamics of noninteracting trapped fermions
Physical Review A, 2015 Motivated by several experimental efforts to understand spin diffusion and transport in ultracold fermionic gases, we study the spin dynamics of initially spin-polarized ensembles of harmonically trapped non-interacting spin-1/2 fermionic atoms, subjected to a magnetic field gradient.

Demagnetization dynamics of C-doped FePt film
Acta Physica Sinica, 2016 Magneto-optical information storage has been a hot research subject for several years. FePt exhibits abundant physical properties and has received much attention as a candidate material. Its alloy film with perpendicular anisotropy and small grain size has important applications in magnetic recordings due to the large intrinsic magnetic anisotropy ...

Dynamic cantilever magnetometry of individual ferromagnetic nanotubes [PDF]
, 2014 In this thesis, we focus on a particular aspect of nanotechnology, namely the understanding of magnetic states in nanometer-scale objects. Describing microscopic magnetization states and reversal is particularly important for the development of magnetic ...

Electron-phonon scattering dynamics in ferromagnetic metals and their influence on ultrafast demagnetization processes [PDF]
Physical Review B, 2011 We theoretically investigate spin-dependent carrier dynamics due to the electron-phonon interaction after ultrafast optical excitation in ferromagnetic metals. We calculate the electron-phonon matrix elements including the spin-orbit interaction in the electronic wave functions and the interaction potential.

Robust Model-Free Nonsingular Terminal Sliding Mode Control for PMSM Demagnetization Fault
IEEE Access, 2019 In this paper, a robust model-free nonsingular terminal sliding-mode control (MFNTSMC) algorithm based on the ultra-local model is proposed to reduce the influence of permanent magnet (PM) demagnetization for PM synchronous motors (PMSMs).
