I study how mechanical strain reshapes magnetism in thin films, and use that physics to build flexible planar Hall effect sensors with sub-200 pT resolution at the Klein Group, Bar-Ilan University.
I am a Ph.D. candidate in the Klein Group at Bar-Ilan University, working at the intersection of magnetism, strain, and device fabrication.
My research asks a practical question: what happens to a magnetic sensor when you bend it? I fabricate planar Hall effect devices on flexible substrates, characterize how strain modifies their magnetic anisotropy, and turn that coupling into a feature: devices that sense magnetic field and strain at once.
Alongside research, I operate the Nano-Fabrication Center at BINA, supporting cleanroom work like sputtering, lithography, and thin-film deposition for research groups across the institute.

Shrinking the ellipse short axis from 200 to 20 µm raises the anisotropy field from 12 to 120 Oe and extends the operating field range tenfold. The optimized 50 µm device reaches 7.7 nT/√Hz at 10 Hz.

PhD thesis · Klein Lab
Bending a sensor to a 10 mm radius flips its magnetization easy axis and tunes the effective anisotropy field from 7.2 to 17.8 Oe, reversibly. The same physics lets one device read magnetic field and strain at once.
