TLDR
In this paper, Neel's theory is used to derive the expression describing the disaccommodation of the complex initial susceptibility in an alternating field in dependence on temperature, frequency of the field and concentration of relaxators.Abstract:
Neel's theory is used to derive the expression describing the disaccommodation of the complex initial susceptibility in an alternating field in dependence on temperature, frequency of the field and concentration of relaxators. In addition to the disaccommodation of the real part the relaxation of the imaginary part of the initial susceptibility and that of the loss angle are predicted. The physical meaning of derived expressions have been discussed and the phenomena which can influence the aftereffect measurements have been mentioned.read more

Purification of iron to low carbon and nitrogen contents by annealing
TL;DR: The residual carbon content was found to depend not solely on the method of hydrogen purification but also on the type and state of the purification apparatus and on the annealing procedure.

Was it necessary to introduce the notion “relaxor ferroelectrics”? - the problem of phase transitions in (Pb,Li½-La½)(Zr,Ti)O3, (Pb,La)(Zr,Ti)O3, Pb(Mg1/3Nb2/3)O3, Pb(In½Nb½)O3. and related materials. 1. model conceptions
TL;DR: In this paper, a phenomenological description of the effects originating in the coexistence of FE and AFE phases is presented, and the behaviour of the discussed systems is analyzed in the frame of the Landau phenomenological model on the basis of the thermodynamic potential taking into account the order parameters of the both mentioned phases.

Peculiarities of ferro-antiferroelectric phase transitions. 5. Relaxation dynamics of interphase domain walls
TL;DR: In this paper, the Vogel-Fulcher relation between phase transformations between FE and AFE phases induced by electric field in that part of the crystal where the interphase boundary moves under the action of the field is obtained.

The influence of the skineffect on the disaccommodation of the initial permeability
TL;DR: In this paper, the influence of the skine effect on the kinematic properties of disaccommodation measurements in metals has been calculated in higher approximations and it is shown that the influence depends not only on the frequency of the measuring field and on the diameter and material constants of the cylindrical specimen but also on the relaxation strength, i.e., on the concentration of relaxators.

Physical Effects in the Vicinity of the Ferroelectric-Antiferroelectric Interface
V. M. Ishchuk,V. L. Sobolev +1 more
TL;DR: In this article, the authors investigated the physical effects caused by the presence of interfaces between the domains of coexisting ferroelectric and antiferroelectric phases in solid solutions with small difference in free energies of the domains.

Interstitials and vacancies in α iron
TL;DR: In this paper, a two-body central force was devised which matched the elastic moduli, was sharply repulsive at close separation, and went to zero midway between the second and third neighboring atoms.

Effect of small quantities of carbon and nitrogen on the elastic and plastic properties of iron
TL;DR: In this article, the elastischen Nachwirkung in reinem und technischem Eisen und in Eisenlegierungen wird diskutiert, insoweit sie durch die Anwesenheit von Stickstoff oder Kohlenstoff in fester Losung verursacht wird.

Théorie du traînage magnétique de diffusion
TL;DR: Theoretie du trainage magnetique de diffusion (ou trainage reversible) as mentioned in this paper is an extension of the trainage de fluctuations theory, in which atomes and rangers interstitiels are agiraient par couplage magnetocristallin entre leur position and the direction of l'aimantation spontanee.
