Which of the following arrangements shows the schematic alignment of magnetic moments of antiferromagnetic substances?
1.
2.
3.
4.
HINT: Domains are oppositely oriented and cancel out each other's magnetic moment.
Explanation:
The substances which have domain structure are oppositely oriented and cancel each other's magnetic field are known as antiferromagnetic substances.
The antiferromagnetic materials are commonly found among the transition metal compounds. Hematite, chromium, alloys of iron manganese and oxides of nickel are the examples of antiferromagnetic material.
