Direction: The following item consists of two statements, one labelled...
Concept:
Ferroelectric material:
- It is characterized by the presence of a remnant polarization at zero bias voltage and the ability to switch the direction of this polarization
- A ferroelectric material is normally in single-crystalline or polycrystalline form and possesses a reversible spontaneous polarization over a certain temperature range
- There is a critical temperature, called the Curie temperature, which marks the transition from the ordered to the disordered phase
Piezoelectric Effect:
- It is the ability of certain materials to generate an electric charge in response to applied mechanical stress
- When piezoelectric material is placed under mechanical stress, a shifting of the positive and negative charge centres in the material takes place, which then results in an external electrical field
- When reversed, an outer electrical field either stretches or compresses the piezoelectric material
Curie - Weiss law:
According to Curie - Weiss law, the susceptibility of a ferromagnetic material decreases above a certain temperature called curie temperature and it becomes paramagnetic in nature.
The susceptibility is given by
Where,
C = Curie constant,
TC = Curie temperature,
T = Temperature

Where,

TC = Curie temperature,
T = Temperature
All the ferroelectric materials are piezoelectric materials also but all the piezoelectric materials are not ferroelectric materials.
Therefore, statement I is true.
Therefore, statement I is true.
Statement II:
- Ferroelectric materials are also temperature-dependent.
- For T > Tcurie, these materials converted into the paramagnetic.
- These materials undergo transformation above the critical temperature.
