Insights into the Dielectric Loss Mechanism of Bianisotropic FeSi/SiC Composite Materials
ACS Omega, 2020 High magnitudes of permittivity with the permeability of the materials help to absorb electromagnetic waves more efficiently. Snoek’s limit directly puts a constraint on the enhancement of the permeability of the material.

On the power spectrum of magnetization noise [PDF]
, 2001 Understanding the power spectrum of the magnetization noise is a long standing problem. While earlier work considered superposition of 'elementary' jumps, without reference to the underlying physics, recent approaches relate the properties of the noise ...

High‐Efficiency Thermal Battery Regulated by Ultralow Magnetic Fields
Small Science, Volume 6, Issue 1, January 2026.A magneto‐responsive composite is reported that, for the first time, achieves a noncontact phase transition with an ultralow magnetic field (≈0.04 T). It exhibits a colossal entropy change of ≈507.6 J kg−1 K−1, an enthalpy of 181.1 J g−1, and a ≈47.6 K temperature rise, alongside enhanced thermal conductivity and heat‐release efficiency, making it ...

Computer simulations of iron in magnesium silicate perovskite [PDF]
, 2008 We use atomistic computer simulation techniques to investigate the site partitioning of iron in (Mg,Fe)SiO_{3} perovskites. Our calculations predict that the most energetically favourable reaction for iron substitution will be a direct exchange of Fe^{2+}
