What is antiferromagnetism with example?

Antiferromagnetic materials occur commonly among transition metal compounds, especially oxides. Examples include hematite, metals such as chromium, alloys such as iron manganese (FeMn), and oxides such as nickel oxide (NiO).

What are examples of ferromagnets?

Common examples of ferromagnetic substances are Iron, Cobalt, Nickel, etc. Besides, metallic alloys and rare earth magnets are also classified as ferromagnetic materials. Magnetite is a ferromagnetic material which is formed by the oxidation of iron into an oxide.

What are examples of Ferrimagnetism?

Ferrimagnetism is exhibited by ferrites and magnetic garnets. Example: magnetite (iron(II,III) oxide; Fe3O4) and yttrium iron garnet are ferrimagnet.

What are some examples of metals with ferromagnetism?

List of Magnetic Metals

  • Iron. Iron is an extremely well-known ferromagnetic metal.
  • Nickel. Nickel is another popular magnetic metal with ferromagnetic properties.
  • Cobalt. Cobalt is an important ferromagnetic metal.
  • Steel.
  • Stainless Steel.
  • Rare Earth Metals.
  • Aluminium.
  • Gold.

Is example of antiferromagnetic material?

Hematite, chromium, alloys of iron manganese and oxides of nickel are the examples of antiferromagnetic material.

Is Fe3O4 antiferromagnetic?

The magnetic interaction among iron ions at octahedral and tetrahedral sites is antiferromagnetic and that among octahedral ions is ferromagnetic; overall a ferrimagnetic arrangement of Fe3O4. Therefore, the net magnetic moment in Fe3O4 is due to Fe2+ ions (4 μB).

Which of the following is not an example of ferromagnetic substance?

Aluminium (Al) is not a ferromagnetic in nature.

How ferrimagnetism arises in substances give an example of substance showing ferrimagnetism?

Ferrimagnetism arises in substances by: Examples are Fe3O4, CuFe2O4 etc. Ferrimagnetism arises because solid material that contains a magnetic field associated atom produces a magnetic field in the whole material such that they align in a parallel and antiparallel manner randomly.

Why is gadolinium ferromagnetism?

Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with an attraction to a magnetic field higher than that of nickel. Above this temperature it is the most paramagnetic element.

Is Fe3O4 antiferromagnetic substance?

At normal temperature, Fe3O4 is ferrimagnetic. As opposed to antiferromagnetism, ferrimagnetic materials have populations of atoms with opposite magnetic moments.

Is TiO2 antiferromagnetic?

TiO2 is not ferromagnetic because the Ti in TiO2 has no unpaired electrons and hence, it cannot be paramagnetic and therefore, it is not ferromagnetic.
