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>

Out-of-plane ferroelectricity and robust magnetoelectricity in quasi two-dimensional materials
<p>Thin film ferroelectrics have been pursued for capacitive and nonvolatile memory devices. They rely on polarizations that are oriented in an out-of-plane direction to facilitate integration and addressability with CMOS architectures. The internal depolarization field, however, formed by surface charges can suppress the out-of-plane polarization in ultrathin ferroelectric films that could otherwise exhibit lower coercive fields and operate with lower power. Here we unveil stabilization of a polar longitudinal optical (LO) mode in the <em>n</em>=2 Ruddlesden–Popper family that produces out-of-plane ferroelectricity, persists under open-circuit boundary conditions, and is distinct from hyperferroelectricity. Our first-principles calculations show the stabilization of the LO mode is ubiquitous in chalcogenides and halides and relies on anharmonic trilinear mode coupling. We further show that the out-of-plane ferroelectricity can be predicted with a crystallographic tolerance factor, and we use these insights to design a room-temperature multiferroic with strong magnetoelectric coupling suitable for magneto-electric spin-orbit transistors. </p>
Magnetic Distance Estimation Data from Gait Experiments with Magnetoelectric Sensors
<h2>Overview</h2> <p><br>This is the "Magnetic Distance Estimation Data from Gait Experiemtns with Magnetoelectric Sensors" dataset. <br>It represents a pilot study on magnetic motion tracking with novel magnetoelectric sensors during treadmill walking.<br>Therefore, it contains both technical (calibration) data and clinical (gait) data of five healthy participants.</p> <p>Example scripts for loading and processing data are available in the linked respository.</p> <p>The dataset is formatted according to the Brain Imaging Data Structure. See the `dataset_description.json` file for the specific version used.</p> <p>The work was supported by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) through the Collaborative Research Center CRC 1261 Magnetoelectric Sensors: From Composite Materials to Biomagnetic Diagnostics. The data was recorded in the project B9 on "Magnetoelectric Sensors for Movement Detection and Analysis".</p> <p>All measurements were approved by the ethics committee of Kiel University (File number: A122/20) and conducted in accordance with the Declaration of Helsinki.</p> <h2><br>Details about the experiment</h2> <p><br>Magnetic motion tracking enables a relative tracking, in which the distance between each sensor and actuator node can be estimated. <br>The full setup contains two actuator nodes (a0, a1) and four sensor nodes (s0, s1, s2, s3).<br>Each actuator-sensor pair produces nine magnetic signals (x,y,z by x,y,z) as well as three magnetic dipole moment signals that represent the currents through the coils (actuators).<br>Additionally, each node was tracked with an optical motion capture (OMC) system. The resulting position and orientation data of the attached rigid body act as a reference (ground truth) to evaluate the magnetic estimation. <br>Subfolders sub-01 to sub-08 each contain up to three calibration tasks which each contain between 60 and 120s of arbitrary movement of one coil (wand-mounted) around one stationary sensor (base).<br>Subfolders sub-09 to sub-13 each contain two 120s walking tasks (0.5 and 1 m/s) of five subjects in total with the full sensor and actuator setup. Two actuators were mounted to the shanks, two sensors to the thighs and two sensors were placed stationary next to the threadmill. <br>The dataset also contains a folder with derived data, which contains calibration parameters for each actuator-sensor pair. See the provided matlab script for details on how to load, visualize, and compare the results.</p>

Investigation of adhesion layers for the deposition of magnetostrictive CoxFe(1-x) films on ScyAl(1-y)N films for magnetoelectric MEMS sensors
<p>For magnetoelectric film stacks, Co/Fe multilayers are deposited on piezoelectric (Sc)AlN films on Si/SiO2 substrates and subsequently annealed by rapid thermal annealing (RTA) to create a Co-Fe alloy phase. In this study, the influence of an optional adhesion layer of 5 nm Cr or Zr on the phase transformation and interlayer properties was investigated. The dataset provided contains logfiles from the RTA process, raw data of X-ray diffraction (XRD), enery dispersive X-ray spectroscopy (EDS) measurements and scanning electron microscope (SEM) images of focused ion beam (FIB) prepared cross-sections. </p> <p> </p> <p>Results published in:</p> <p>H.
