Ultrafast optical demagnetization manipulates nanoscale spin structure in domain walls

During ultrafast demagnetization of a magnetically ordered solid, angular momentum has to be transferred between the spins, electrons, and phonons in the system on femto-and picosecond timescales. Although the intrinsic spin-transfer mechanisms are intense ...

Magnetic domain wall propagation under ferroelectric control

Nava Setter, Igor Stolichnov, Harry Joseph Trodahl, Sebastian Riester, Evgeny Mikheev

Control of magnetic domain walls (DWs) and their propagation is among the most promising development directions for future information-storage devices. The well-established tools for such manipulation are the spin-torque transfer from electrical currents a ...

Current-induced domain wall motion in nanoscale ferromagnetic elements

The manipulation of a magnetic domain wall (DW) by a spin polarized current in ferromagnetic nanowires has attracted tremendous interest during the last years due to fundamental questions in the fields of spin dependent transport phenomena and magnetizatio ...

Magnetization Reversal Dynamics in Ferromagnetic Semiconductors

Liza Herrera Diez

This thesis is dedicated to the study of the magnetization reversal dynamics in compressively strained (Ga,Mn)As and differently functionalized (Ga,Mn)As materials. In the first part the domain wall dynamics of pure (Ga,Mn)As/GaAs materials is in the focus ...

Effects of magnetism in superconducting hybrid structures

Benoît Crouzy

In this thesis we study various effects of magnetism in proximity structures, composed of superconducting electrodes in contact with a normal metal. Magnetism can be present in the system through the Zeeman and the orbital coupling. Proximity structures of ...

Ferromagnetism in Co-7(TeO3)(4)Br-6: A byproduct of complex antiferromagnetic order and single-ion anisotropy

Ivica Zivkovic, Helmuth Berger

Pronounced anisotropy of magnetic properties and complex magnetic order of a new oxi-halide compound Co-7(TeO3)(4)Br-6 has been investigated by powder and single-crystal neutron-diffraction, magnetization, and ac susceptibility techniques. Anisotropy of su ...

2009

Partially oxidized fcc FePd and FePt nanoparticles with mean diameters of 5 and 3 nm, respectively, were synthesized by a reverse micelle polyol process. In situ measurements of magnetic and structural properties during annealing showed a large increase in ...

2009

This thesis addresses the growth and magnetic characterization of 2D bimetallic nanostructures deposited by atomic beam epitaxy (ABE) on Pt(111). These structures possess both tunable high perpendicular magnetic anisotropy (PMA) and magnetic moment. These ...

Magnetic anisotropy of paramagnetic and ferromagnetically ordered state of single crystal BaVSe3

László Forró, Helmuth Berger, Ana Akrap

Anisotropic magnetism of single crystal BaVSe3 was Studied for the first time by the combination of the susceptibility and torque methods. As reported previously for polycrystalline sample, BaVSe3 undergoes ferromagnetic ordering below 43 K. Well above fer ...

Mode localization transition in ferromagnetic microscopic rings

Dirk Grundler

We present a combined experimental, computational, and semianalytical study of the magnetization dynamics of permalloy disks and nanostructured rings with a systematically varied ring width. We investigate the dynamics of the quasisaturated state. In the c ...
