RELAXOR FERROELECTRIC Meaning and
Definition
-
Relaxor ferroelectric refers to a type of material that exhibits a unique combination of characteristics from both relaxor and ferroelectric materials. It is a specific class of dielectric materials that has garnered significant attention in the field of condensed matter physics and material science.
A relaxor ferroelectric is characterized by its ability to exhibit both ferroelectric and relaxor behaviors under certain temperature and electric field conditions. Ferroelectric materials possess a spontaneous electric polarization that can be reversed by an applied external electric field, while relaxor materials exhibit a random electric polarization that is sensitive to temperature changes and electric fields. Relaxor ferroelectrics display a behavior that lies between these two, with disorderly polarized regions that can be reoriented by applied electric fields.
The key defining feature of relaxor ferroelectric materials is the presence of a broad and frequency-dependent dielectric response. This behavior is often explained in terms of random dipole fluctuations, which deviate from a typical ferroelectric material's constant polarization response. These fluctuations result in a high dielectric constant, leading to improved energy storage capabilities and enhanced piezoelectric properties.
Relaxor ferroelectrics find extensive applications in various fields, including electro-optic devices, capacitors, sensors, actuators, and memory devices. The unique combination of properties displayed by these materials makes them highly desirable for technology advancements, especially in fields that require high sensitivity to electric fields and temperature variations.

Etymology of RELAXOR FERROELECTRIC
The term "relaxor ferroelectric" is a scientific term used to describe a certain type of ferroelectric material that exhibits strong relaxor behavior.
The term "ferroelectric" comes from the combination of the Latin word "ferro" meaning "iron" and the English word "electric". Ferroelectric materials are materials that have a spontaneous electric polarization that can be reversed by the application of an external electric field. The term was coined in the early 20th century when ferroelectricity was first discovered in certain crystals.
The term "relaxor", on the other hand, comes from the verb "to relax", meaning to make or become less tense or rigid. In the context of ferroelectric materials, "relaxor behavior" refers to the unique electrical properties exhibited by certain materials where the transition between polar and non-polar states is more disordered compared to traditional ferroelectric materials.
