In this paper, a (2-2) connectivity magnetoelectric (ME) laminate integrates multiple layers of FeSiB alloy (Metglas) and Pb (Mg, Nb) O3-PbTiO3 (PMN-PT) single crystal, achieving a remarkable ME coupling coefficient of 2033.4 V/Oe·cm (sevenfold rise) by laser thermal annealing treatment. Here, the laser-induced nanostructures on Metglas, with oxidized insulation layer and soft and hard magnetic dipole layer improve the Magneto-electric-mechanical coupling with a mechanical quality factor exceeding 350. More importantly, the interaction between amorphous and nanocrystalline dipoles triggers an EB effect, leading to self-biasing performance of 67.45 V/Oe·cm. Furthermore, the composite exhibits excellent passive DC magnetic detection limit of 22 nT, and an improved weak AC magnetic detection limit down to 383 fT. These explorations offer the potential to enhance passive current measurement, underwater communication, extend weak magnetic positioning, and extend brain magnetic detection. magnetoelectric coupling laser thermal annealing self-biased Full Text Additional Declarations (Not answered) Cite Share Download PDF Status: Published Journal Publication published 15 Jul, 2025 Read the published version in Microsystems & Nanoengineering → Version 1 posted Editorial decision: revise 14 Nov, 2024 Review # 2 received at journal 05 Nov, 2024 Reviewer # 2 agreed at journal 25 Oct, 2024 Review # 1 received at journal 22 Oct, 2024 Reviewer # 1 agreed at journal 15 Oct, 2024 Reviewers invited by journal 15 Oct, 2024 Submission checks completed at journal 10 Oct, 2024 Editor assigned by journal 09 Oct, 2024 First submitted to journal 09 Oct, 2024 You are reading this latest preprint version Research Square lets you share your work early, gain feedback from the community, and start making changes to your manuscript prior to peer review in a journal.
