Question

Give one property which does not relate to ferrimagnetism ?

Answer 1

Hint:When a magnetic field is applied across a material then on the basis of their response to the magnetic field they are mainly classified as: diamagnetic, paramagnetic, ferromagnetic. Domain of a magnetic material is defined as the region in which the magnetic moments of electrons are aligned parallel or in direction of magnetic field.

Complete answer:
The materials in which magnetic moments have a tendency to be aligned in the same direction even without external magnetic fields are ferromagnetic materials. Although the direction of all domains is not the same and due to this they remain unmagnetised but when a magnetic field is applied the domain rotates and gets aligned in the direction.

Thus, they are strongly magnetized by electric fields. Examples are Fe, iron oxides etc.On the other hand ferromagnetic substance shows similar behaviour as ferromagnetic substances like having magnetic moment even in not presence of field and also behaves as paramagnetic at temperature more than Curie temperature. Because there are equal numbers of parallel and antiparallel arrangements of domains which cancels out each other's effect.

Due to which ferromagnetic substances are not strongly attracted by magnetic fields, example is magnetite.

Note:Ferrimagnetic substances behave as ferromagnetic substances below the Curie temperature. Curie temperature is that temperature at which some magnetic substances have a change in their magnetic properties.
