Flexible multiferroic PVDF/CoFe2O4 composite films for pyroelectric energy conversion

Harnessing the Induced Magnetostrictive Effect in Fully Flexible Fiber-Based Magnetoelectric Composites for Improved Stray Magnetic Energy Harvesting

“…The slender magnetic hysteresis loop observed in the NBE composite signifies its soft magnetic characteristics, rendering it easily magnetizable and demagnetizable. The reported M s and H c values in our study align with recently published data. − The magnetic characteristics of the inverse spinel structure (MFe 2 O 4 , M = Ni/Co) with the formula (MFe) B (Fe) A can be elucidated by considering the distribution of the cations. In this structure, the magnetization is influenced by the arrangement of M 2+ ions, which occupy octahedral sites, while both Fe 2+ and Fe 3+ ions are found in both the octahedral (B) and tetrahedral (A) sites.…”
