Temperature Aging

In this study, a room temperature aging behavior of Ba(Ti0.99Fe0.01)O3 was investigated. It was found that the dielectric constant decreased with time and ferroelectric P-E hysteresis loops became constricted loops after aging. Moreover, the room temperature aging behavior under various stresses was also observed. It was found that the relative changes of dielectric constant with time of Ba(Ti0.99Fe0.01)O3 ceramics under stress were lower than those under the stress-free condition. For P-E hysteresis loop measurement, it can be observed that P-E hysteresis loop of Ba(Ti0.99Fe0.01)O3 ceramics became constricted loops and remanant polarizations (Pr), saturated polarizations (Ps) were decreased after aging under all stress levels. These results suggested that the applied stress may partly clamp the domain wall motion, and altered the aging behavior of the ceramics.

Shifted Hysteresis Loop

The tuning exchange bias HE at martensitic state of Ni50Mn36Sn14 alloy has been investigated by means of hysteresis loop measurement. It was found that the whole loop can be tuned by HFC from a double-shifted to a single-shifted hysteresis loop, leading to an appearance of maximum HEat HFC = 0.5 kOe. This behavior could be ascribed to the competition between two types of AFM clusters and HFC,which exhibits predominantly atlow HFC range, while the competition between FM clusters and HFC, which becomes predominant at high HFC range.
