Ion Diffusion and Disaccommodation in Ferrites
Japanese Journal of Applied Physics, 1968In various mixed ferrites, the relationship between disaccommodations (DA) and cation vacancy densities was investigated, the latter being estimated from the diffusion coefficients of isotopes. The relaxation time of DA–I observed at approximately 250°C was in agreement with an extrapolated value from the cation diffusion at elevated temperatures ...

Magnetic disaccommodation in Sr doped magnetite
Le Journal de Physique IV, 1998The relaxation of the initial permeability is measured in polycrystalline strontium doped magnetite with initial compositions SrO-nFe 2 O 3 , with n ranging between n=16 and n=122.34. The samples have been sintered at 1300° C in a reducing CO 2 atmosphere and rapidly quenched to provide the presence of crystal vacancies In the temperature range ...

Disaccommodation in manganese-zinc ferrite
Journal of Physics D: Applied Physics, 1971The temperature spectrum of disaccommodation for manganese-zinc ferrous-ferrite toroidal specimens is studied using two methods of magnetic shock. One of these methods, namely, disturbance using a capacitor discharge (ac demagnetization), produces a broad maximum in the disaccommodation against temperature characteristic.

The magnetic disaccommodation in aluminium ferrites
Journal of Magnetism and Magnetic Materials, 1999Abstract The domain wall stabilization processes in aluminium substituted magnetite is investigated by means of disaccommodation techniques. The time evolution of the initial magnetic susceptibility after sample demagnetization is measured for polycrystalline specimens with nominal composition Al x Fe 3− x O 4 , 0⩽ x ⩽1, around room temperature ...

Anomalous magnetic disaccommodation in yttrium iron garnet
Materials Letters, 1998Abstract An alternative approach to account for the oxygen loss at sintering temperatures in YIG allows an explanation to the not yet elucidated accommodation effect observed in the magnetic disaccommodation spectrum of nominal stoichiometric samples below 130 K; i.e., the observed time increase of the initial permeability μ i after ...

Disaccommodation in Fe-Al alloys
Physica Status Solidi (a), 1970In Fe-Al alloys only two regions of disaccommodation are found. The first at about 0°C is caused by the Snoek-effect and the second at about 400°C by reorientation of substituted Al atoms. The temperature dependence of the disaccommodation agrees well with the calculated one.

Disaccommodation in a nearly zero magnetostriction metallic glass
Journal of Magnetism and Magnetic Materials, 1984Abstract Disaccommodation (DA) and accommodation (A) processes showing up in the time dependence of the permeability were investigated in Fe-Co-based metallic glasses with nearly zero magnetostriction. It was found that in some alloys there are anomalously large DA and A processes.
