Engineering skyrmions in transition-metal multilayers for spintronics
<p>Magnetic skyrmions are localized, topologically protected spin structures that have been<br> proposed for storing or processing information due to their intriguing dynamical and transport<br> properties. Important in terms of applications is the recent discovery of interface stabilized<br> skyrmions as evidenced in ultra-thin transition-metal films. However, so far only skyrmions at<br> interfaces with a single atomic layer of a magnetic material were reported, which greatly<br> limits their potential for application in devices. Here we predict the emergence of skyrmions<br> in [4d/Fe2/5d]n multilayers, that is, structures composed of Fe biatomic layers sandwiched<br> between 4d and 5d transition-metal layers. In these composite structures, the exchange<br> and the Dzyaloshinskii–Moriya interactions that control skyrmion formation can be tuned<br> separately by the two interfaces. This allows engineering skyrmions as shown based on<br> density functional theory and spin dynamics simulations.</p>
Images for "Nano-scale magnetic skyrmions in metallic films and multilayers: a new twist for spintronics"
<p>Magnetic skyrmions are chiral quasiparticles that show promise for the transportation and storage of information. On a fundamental level, skyrmions are model systems for topologically protected spin textures and can be considered as the counterpart of topologically protected electronic states, emphasizing the role of topology in the classification of complex states of condensed matter. Recent impressive demonstrations of control of individual nanometer-scale skyrmions—including their creation, detection, manipulation and deletion—have raised expectations for their use in future spintronic devices, including magnetic memories and logic gates. From a materials perspective, it is remarkable that skyrmions can be stabilized in ultrathin transition metal films, such as Fe—one of the most abundant elements on earth—if these are in contact with materials that exhibit high spin-orbit coupling. At present, research in this field is focused on the development of transition-metal-based magnetic multilayer structures that support skyrmionic states at room temperature and allow for precise control of skyrmions by spin-polarized currents and external fields.</p>
Radiation hardness of ultrabroadband spintronic terahertz emitters: En-route to a space-qualified terahertz time-domain gas spectrometer
<p>Data for the publication "Radiation hardness of ultrabroadband spintronic terahertz emitters: En-route to a space-qualified terahertz time-domain gas spectrometer" accepted for publication in Applied Physics Letters. The following datasets are provided: time-domain raw data (dry vs ambient conditions) and corresponding Fourier amplitude spectra as well as the impedance of the spintronic THz emitter vs frequency, THz transmission Fourier amplitude spectra from a spintronic THz emitter propagating through a gas cell with CO2 and N2, CO2 absorption coefficient vs frequency from THz transmission measurements through the gas cell, electro-optic THz signals and corresponding Fourier amplitude spectra for gamma and proton irradiated spintronic THz emitters as well as THz amplitudes vs irradiation dose/proton fluence.</p>
360° polarization control of terahertz spintronic emitters using uniaxial FeCo/TbCo2/FeCo trilayers
<p>The attached files contain raw data of terahertz spintronic emitters (STE) measured with terahertz time-domain spectroscopy (THz-TDS) and vibrating sample magnetometry (VSM). The file name indicates what was measured and the individual column names in the file describe the measured quantities.</p> <p>STE_comparison_reflection.csv provides a comparison of the performance of the proposed spintronic emitter integrated on various substrates in a reflection configuration of THz-TDS. STE_comparison_transmission.csv compares the developed spintronic emitter with a reference sample in a transmission configuration. The data files starting with 'VSM_magnetization_' contain VSM measurements of orthogonal magnetization vectors for FeCo, TbCo2, and the proposed trilayer for both easy (EA) and hard axes (HA). The magnetic hysteresis of the spintronic emitter is shown in the files VSM_hysteresis_STE.csv, TDS_hysteresis_mx_STE.csv, and TDS_hysteresis_my_STE.csv obtained using THz-TDS and VSM measurement techniques. The file TDS_polarization_rotation.csv demonstrates magnetically controlled polarization rotation of terahertz waveforms. The last file, TDS_quartz_analysis.csv, involves an application example of using a spintronic emitter for terahertz spectroscopy in quartz analysis.</p>
Fully reversible magnetoelectric voltage controlled THz polarization rotation in magnetostrictive spintronic emitters on PMN-PT
<p>The files include experimental data to demonstrate magneto-electric control of terahertz polarization of spintronic emitters. The files called "Vertical E-field amplitude" and "Horizontal E-field amplitude" describe the terahertz wave rotation for orthogonal polarizations measured for different values of applied voltage. The files "E-field peak rotation" show the control of polarization at the peak of the terahertz signal and differs by magnetic field bias (A/m). The measurement of the strain creating the magnetoelestic anisotropy can be found in the file "pmn-pt-strain". Files "Hysteresis - STEmulti-PMN-PT" contain magneto-hysteresis loops for easy (EA) and hard axis (HA).</p>
