ferrimagnetism class 12

They can be permanently magnetized. (iii) Ferrimagnetism: Ferrimagnetism is observed when the magnetic moments of the domains in the substance are aligned in parallel and antiparallel directions in unequal number resulting in some net magnetic moment, e.g., Fe 3 O 4 (magnetite) and ferrites like MgFe 2 O 4 , etc. Compounds belong to 12 – 16 group are formed by the combination of elements of 12 and 16 groups. The magnetic properties of a solid are the result of the magnetic property of the atoms or ions of these solids. by Anand Meena. Solid state class 12 CBSE 1. Some ferrimagnetic materials are YIG (yttrium iron garnet), cubic ferrites composed of iron oxides and other elements such as aluminum, cobalt, nickel, manganese and zinc, hexagonal ferrites such as PbFe 12 O 19 and BaFe 12 O 19, and pyrrhotite, Fe 1-x S. [3] Explain how you can determine the atomic mass of an unknown metal if you know its mass density and the dimensions of unit cell of its crystal. 12. These substabces are magnetised in a magnetic field in the same direction. It arises because the substances are magnetized in the same direction of the applied magnetic field. These substances can be permanently magnetised with the help of strong electrostatic field.

While the compound of 13–15 group compounds are prepared by combining elements of group 13 and group15. Magnetic Property of Solids. Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.In physics, several different types of magnetism are distinguished. The metal ions of ferromagnetic substances are grouped together into small regions called domains in solid state. Solid composed of molecules as constituent particles. From this viewpoint, ferromagnetism is a particular case of ferrimagnetism in which a substance contains only one sublattice, and antiferromagnetism is a particular case in which all sublattices consist of identical magnetic ions and J = 0.

In these domains, large numbers of atom's moments (10 12 to 10 15) are aligned parallel so that the magnetic force within the domain is strong. 2. Crystal - Crystal - Ferrimagnetic materials: Ferrimagnetism is another type of magnetic ordering. More specifically the magnetism and magnetization of a solid will depend on the movement of electrons in an atom.It can thus be said that each electron of an atom behaves like a magnet, lending the whole solid its magnetic property. Examples include Fe 3 O 4 (magnetite), ferrites such as MgFe 2 O 4 and ZnFe 2 O 4. Some ferrimagnetic materials are YIG (yttrium iron garnet), cubic ferrites composed of iron oxides and other elements such as aluminum, cobalt, nickel, manganese and zinc, hexagonal ferrites such as PbFe 12 O 19 and BaFe 12 O 19, and pyrrhotite, Fe 1-x S.
