Article Title: Highly magneto-electric-mechanical coupling effect in self-biased magnetoelectric composite induced by laser thermal annealing

doi: 10.1038/s41378-025-00875-w

Figure Lengend Snippet: a Magnetoelectric coupling coefficients: comparative analysis of self-biased and ME laminates under optimal DC bias conditions. b Sensitivity metrics: limit of detection (LoD) and power spectral density (PSD) for the self-biased laminate. c Hysteresis behavior: DC response curves for both SME and ME laminates. d Unbiased coupling efficiency: Magnetoelectric coupling in SME and ME laminates without DC bias application. e Noise Characterization: Direct current noise levels associated with the SME laminate. f Near-Zero DC Hysteresis: Comparative hysteresis curves of SME and ME laminates in proximity to DC zero

Article Snippet: However, it is worth noting that there is a significant breakthrough enhancement in magnetoelectric response at resonant frequency and LoD of SME laminate at resonant frequency due to its exponentially increasing Q m and Δ E. Additionally, the performance indices of (2-2) ME laminates, obtained through a comparative analysis of various Metglas annealing studies, are presented in Table .
