ABSTRACT
The article discusses analysis on the reactive domain walls in materials physics. Topics include domain walls as natural borders in ferroelastic and ferromagnetic materials, production of crystallographic phases in bulk materials, and reaction of domain walls to stress. Diagrammatic presentation of domain-wall arrangement and atomic motions is presented.

    We investigate the domain wall speed of a ferroelectric PbZr0.48Ti0.52O3 (PZT) thin film using an atomic force microscope incorporated with a mercury-probe system to control the degree of electrical fatigue. The depolarization field in the PZT thin film decreases with increasing the degree of...

    We have investigated the pinning and depinning of "virtual" domain walls in planar magnetic nanowires. Such virtual walls are created when a conventional domain wall becomes annihilated at a narrow gap between two segments of a discontinuous nanowire. By using focused magneto-optical Kerr effect...

    The ferroelectric switching kinetics of BiFeO3 capacitors grown on a piezoelectric substrate has been investigated in different strain states and at various temperatures. The switching behavior is in good agreement with the Kolmogorov-Avrami-Ishibashi model. The effect of reversible biaxial...

    Ferroelectric materials subjected to a DC electric field have their dielectric permittivity which decreases with time. This is connected to the reorganization of the domain walls to achieve a more stable configuration. We propose here to study the domain walls motion when the material is...

    The polarization reversal and dynamic hysteresis of ferroelectrics specially with double hysteresis-like loops were investigated by using CuO-doped (Na0.5K0.5)NbO3 ceramics. The variation of the hysteresis area and current density clearly suggests three stages of the polarization reversal. It...

    Charge dipole moment and spin moment rarely coexist in single-phase bulk materials except in some multiferroics. Despite the progress in the past decade, for most multiferroics their magnetoelectric performance remains poor due to the intrinsic exclusion between charge dipole and spin moment. As...
