What is Ferroelectric domains explain in details?
Ferroelectric domains are regions within a ferroelectric material where the electric dipoles are aligned in a specific direction. These domains can switch orientation when an external electric field is applied, allowing the material to exhibit ferroelectric properties. The presence of domains allows ferroelectric materials to have unique properties such as piezoelectricity and non-volatile memory storage.
What is the smallest part of a substance that has all the porperties of the substance?
Molecules are the smallest part of a substance. Molecules have all the properties of a substance.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
Is the amount of a substance in a given volume the concentration of the substance?
Ye.. the concentration of a substance is measured as the amount of substance per unit volume. Accordingly, the amount of a substance in per unit volume is the concentration of the substance.

Iron is ferroelectric but copper is not why?
Iron is not ferroelectric. Ferroelectric materials possess a permanent electric dipole moment that can be reversed by an external electric field. Copper does not have this property because it lacks a crystal structure that allows for the alignment of dipoles.
Is lead zirconium titanate ferrous?
Not ferrous, but ferroelectric !
What is the meaning of Ferroelectric?
In physics the ferroelectric effect is an electrical phenomenon whereby certain materials may exhibit a spontaneous dipole moment, the direction of which can be switched between equivalent states by the application of an external electric field. Placing a ferroelectric material between two conductive plates creates a ferroelectric capacitor. Ferroelectric capacitors exhibit nonlinear properties and usually have very high dielectric constants. The fact that the internal electric dipoles can be forced to change their direction by the application of an external voltage gives rise to hysteresis in the "polarization vs voltage" property of the capacitor. In this case, polarization is defined as the total charge stored on the plates of the capacitor divided by the area of the plates. Hysteresis means memory and ferroelectric capacitors are used to make ferroelectric RAM for computers and RFID cards. Above retrieved from Answers.com Viper1
Ferroelectric ram as both ram and rom?
only rom
How can you measure the hysteresis loop of the ferroelectric materials and what is the name of the instruments used for the measurements of the hysteresis loop?
The hysteresis loop of ferroelectric materials can be measured using a ferroelectric tester or a precision impedance analyzer. These instruments apply a voltage sweep to the material and measure the resulting polarization response, capturing the hysteresis loop which shows the relationship between polarization and applied electric field.
Why electrocaloric effect observed in ferroelectric polymers only?
Its not true that electrocaloric effect (ECE) is observed only in ferroelectric polymers. ECE can be found in any typical dielectric material. If polarization switches from one direction to the other upon application or withdrawl of electric filed, the temperature of the material changes. It happens both in organic as well as inorganic materials. It is found that the EC coefficent is high near ferroelectric phase transition temperature.

How does one receive hysteresis?
Hysteresis occurs most commonly in ferromagnetic and ferroelectric materials such as rubber bands and shape-memory alloys. When the material is flexed the atoms often break apart causing hysteresis.
