Magnetic disaccommodation of hydrogen and dislocations in metals

Il Nuovo Cimento B Series 11, 1976
In ferromagnetic materials hydrogen has been observed to give rise to three types of magnetic relaxations: 1) diffusion aftereffect due to a long-range migration of hydrogen within domain walls, 2) orientation after-effect due to the rearrangement of anisotropic hydrogen-impurity complexes, 3) magnetic cold-work peak resulting from a condensed hydrogen

Disaccommodation in Fe-Al alloys

Physica Status Solidi (a), 1970
In 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 manganese-zinc ferrite

Journal of Physics D: Applied Physics, 1971
The 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.

Photomagnetic effects and disaccommodation in Co-doped YIG

Journal of Physics and Chemistry of Solids, 1975
Abstract Y3Fe5O12 (YIG) doped with ≦ 0.01 Co per molecule in combination with small dopes of V or (and) Mn show a decrease of the permeability in the dark (disaccommodation, DA) as well as when irradiated (photomagnetic effect, PE) with white light.

Magnetic disaccommodation in normal spinel structures

Applied Physics A Solids and Surfaces, 1991
Magnetic disaccommodation is investigated for ferrous ferrites with normal spinel structure. This study shows the presence of a new relaxation process in the temperature region IV (≃285 K) that has not been detected in inverse spinels. A numerical analysis of the isochronal spectra reveals that it is composed of two simple Debye processes with ...

Coercivity and disaccommodation on amorphous (Fe1−xRx)80B20

Journal of Magnetism and Magnetic Materials, 1994
Abstract Amorphous ribbons of the composition (Fe 1− x R x ) 80 B 20 (R = Y, Ce, Pr, Nd, Sm, Gd, Ho, Er, Tm, Lu) (0⪯ x ⪯0.08) were studied by means of disaccommodation measurements, pinning field and coercivity measurements. The after-effect scales roughly with the square of the magnetostriction constant.

Permeability disaccommodation and structural stability of metallic glasses

Physica Scripta, 1989
Disaccommodation of permeability (DA), in particular the measuring field Hmp corresponding to the maximum of DA, were investigated in connection with structural stability of a λ = 0 metallic glass. Kinetic curves of Hmp for diversely heat treated toroids were measured and qualitatively evaluated to show the physical meaning of Hmp.

Magnetic Disaccommodation in Ferrites with Nonmagnetic Divalent Substitutions

Japanese Journal of Applied Physics, 2001
The after-effect processes in magnetite with nonmagnetic divalent substitutions are studied by means of disaccommodation techniques. We have recorded at room and high temperatures the time evolution of the initial magnetic susceptibility after sample demagnetization for polycrystalline specimens with nominal composition MxFe3-x O4+

Factors affecting the disaccommodations of amorphous magnetic materials

Journal of Magnetism and Magnetic Materials, 1983
Abstract Disaccommodations of amorphous FeSiB are studied. With the increase of the exciting frequency, the disaccommodation crosses zero and changes its sign thereafter. Tensile stress increases the disaccommodation, while compressive stress decreases it. Low Curie temperature gives low value of disaccommodation.

The influence of the skineffect on the disaccommodation of the initial permeability

Czechoslovak Journal of Physics, 1976
The very sensitive and convenient ac techniques of the disaccommodation measurements in metals are substantially influenced by the skineffect. This influence has been calculated in higher approximations and it is shown that the influence of the skineffect depends not only on the frequency of the measuring field and on the diameter and material ...
