The Use of Kramers-Kronig Relations for Verification of Quality of Ferrite Magnetic Spectra
Electrical, Control and Communication Engineering, 2015 The complex initial permeability (CIP) as a function of frequency is one of the main properties of ferrites. This characteristic (CIP) is measured experimentally, therefore there can be found noisy, doubtful or incomplete parts of the spectrum.

Adsorption isotherm on ferrites
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1994 Tlıe corrosion behaviour of the prepared Materials was studied by mcans of weight-loss techniquc in stagnant solution of (0.01 M) sulphuric acid in presence of thiourea as an inhibitor. Higher concentration of thiourea reduces the corrosion rate of thc samples and proteetion effi- cicncy of thiourea was found to be 80 % for ferrites Proteetion is ...

Microwave power absorption characteristics of ferrites
, 2013 The microwave power absorption characteristics of five ferrites, BaFe 12O19, SrFe12O19, CuFe 2O4, CuZnFe4O4 and NiZnFe 4O4, have been studied by determining the average power absorption patterns of the ferrite slabs using the derived power equations with

Broadening Hard‐Magnet Discovery Beyond Symmetry Constraints via Unified Effective Anisotropy
Advanced Science, EarlyView.A unified effective‐anisotropy descriptor (Keff) extends hard‐magnet screening across all seven crystal systems, beyond the uniaxial restriction of conventional searches. Machine‐learning screening of 9320 known ferromagnets and diffusion‐model generation together yield 38 rare‐earth‐free or ‐lean candidates with DFT‐validated magnetic hardness (κ > 1),
