Strain and Exchange‐Spring Mechanism of (1‐x) Ni0.5Cu0.25Zn0.25Fe2O4 + (x) SrFe11Y1O19 Magnetically Soft–Hard Ferrite Composed Nanoparticles

open access: yesParticle &Particle Systems Characterization, Volume 41, Issue 7, July 2024.
This study explores the creation of soft–hard ferrite composites of NiCuZn‐ and strontium hexaferrites ferrite using sol‐gel autocombustion and physical mixing, revealing the coexistence of soft cubic spinel and hard hexagonal phases. Changes in lattice parameters, grain sizes, and strain are observed for different compositions, significantly impacting

Unraveling Exchange Coupling in Ferrites Nano‐Heterostructures

open access: yesSmall, Volume 20, Issue 10, March 8, 2024.
The magnetization reversal process of a set of nanocomposites with a local texture at the interfaces between SrFe12O19/CoFe2O4 is investigated by combining for the first time, remanence (SFD), FORCs [P(Hc)] and relaxation measurements [S(H)]. The results evidence a strong intergranular exchange coupling, and quantify the size limit of the rigid ...
