TL;DR: This work establishes a unique way to obtain colossal magnetodielectricity, independent of any striction effects, by engineering the asymmetric hopping contribution to the dielectric constant via the tuning of the relative-spin orientations between neighboring magnetic ions in a transition-metal oxide system.

TL;DR: In this paper, the dynamics of a magnetic particle system consisting of ultrafine Fe-C particles of monodisperse nature has been investigated in a large time window, using Mossbauer spectroscopy, ac susceptibility, and zero field cooled magnetic relaxation measurements.

TL;DR: In this article, the authors show that the zero-field-cooled magnetization strongly depends on the time the sample is kept at constant temperature prior to the field application, which is at variance with the common belief that an equilibrium spin-glass state is quickly obtained after cooling in zero field.

TL;DR: In this article, low frequency ac susceptibility measurements on two different spin glasses show that cooling/heating the sample at a constant rate yields an essentially reversible (but rate dependent) $\ensuremath{\chi}(T)$ curve; a downward relaxation of the curve occurs during a temporary stop at constant temperature (aging).

TL;DR: In this paper, magnetization, ac susceptibility, and zero-field-cooled relaxation measurements are carried out for a cluster glass compound of La 0.5 and CoO 0.3.
