Magnetic Bucket Brigade Transport Networks for Cell Transport

Advanced Materials Technologies, Volume 8, Issue 16, August 25, 2023., 2023
By connecting building blocks of multiple curved ferromagnetic elements, a networked pathway is designed for the guided movement of microbeads and labeled cells. Using simple rotating magnetic fields, magnetic carriers and cells are guided deterministically along different paths across a planar surface along the multifunctional magnetic elements.

A magneto‐mechanically coupled material model for magnetic sensor investigation

Proceedings in Applied Mathematics and Mechanics, Volume 22, Issue 1, March 2023., 2023
Abstract We consider coupled micro‐magneto‐mechanics with the aim to understand the processes which underpin magnetic noise in composite magnetoelectric sensors. We formulate a material model within the generalized standard material framework. This approach ensures thermodynamic consistency.

Imaging of Love Waves and Their Interaction with Magnetic Domain Walls in Magnetoelectric Magnetic Field Sensors

Advanced Electronic Materials, Volume 8, Issue 6, June 2022., 2022
The complex interplay of magnetic domain structures with shear waves in magnetoelectric surface acoustic wave sensor devices is imaged by time‐resolved magnetooptical microscopy. The interactions lead to wave reflections, spatial dephasing, and secondary waves.

Local Strain Distribution in ZnO Microstructures Visualized with Scanning Nano X‐Ray Diffraction and Impact on Electrical Properties

Advanced Engineering Materials, Volume 23, Issue 11, November 2021., 2021
Three metal‐coated ZnO microrods are investigated with a combination of strain revealing nano X‐ray diffraction (XRD) and current–voltage curves. It is shown that the crystallite structure inside the microrods has a substantial impact on the electrical properties of the Schottky contact.

Visualizing Intrinsic 3D‐Strain Distribution in Gold Coated ZnO Microstructures by Bragg Coherent X‐Ray Diffraction Imaging and Transmission Electron Microscopy with Respect to Piezotronic Applications

Advanced Electronic Materials, Volume 7, Issue 11, November 2021., 2021
Zinc oxide microstructures coated with gold are investigated by complementary geometric phase analysis on transmission electron micrographs and coherent X‐ray diffraction imaging (CXDI) revealing strain distributions with compressive strain near the Au interface.

Raw Data: Magnetostrictive FeCoSiB coated ZnO Microstructures by Bragg Coherent X-Ray Diffraction Imaging

, 2023
Five sets of raw data from (Fe90Co10)78Si12B10 coated ZnO microstructure (rod) investigated by Bragg coherent X-ray diffraction imaging. FeCoSiB is a magnetostrictive alloy, thus a changing strain is expected for applied magnetic fields.

Highly Sensitive Strain Sensors with FeCoSiB Amorphous Films.

Journal of the Magnetics Society of Japan, 1999
Amorphous FeCoSiB films with high saturation magnetostriction and excellent soft magnetic properties were studied to determine their strain sensitivity. The films were subjected to strain by bending of their substrates, which caused a change in the magnetic anisotropy of films via magnetoelastic coupling.

Signal-to-noise ratio enhanced electrode configurations for magnetoelectric cantilever sensors

AIP Advances, 2020
Magnetoelectric cantilevers consisting of strain-coupled magnetostrictive and piezoelectric (PE) layers are applicable to magnetic-field sensing. For the first bending mode, the magnetic field-induced stress distribution is of equal sign along the ...

Observation of Enhanced Dynamic {\Delta}G effect near Ferromagnetic Resonance Frequency

, 2023
The field-dependence elastic modulus of magnetostrictive films, also called {\Delta}E or {\Delta}G effect, is crucial for ultrasensitive magnetic field sensors based on surface acoustic waves (SAWs).

Sensitivity and noise analysis of SAW magnetic field sensors with varied magnetostrictive layer thicknesses

, 2022
Art.111998In this work surface acoustic Love wave delay line magnetic field sensors with varying magnetostrictive layer thicknesses are discussed. Amorphous FeCoSiB is used as the sensitive layer with a thickness variation in the range of 25-400 nm.
