Ferrimagnetic substance show better magnetism than antiferromagneric substance. Why? |
|
Answer» The key DIFFERENCE between ferromagnetism and antiferromagnetism is that ferromagnetism can be found in materials having their magnetic domains aligned into the same direction WHEREAS antiferromagnetism can be found in materials having their magnetic domains aligned in opposite directions. A magnetic DOMAIN or an atomic moment is a region in which the magnetic fields of atoms are grouped TOGETHER and aligned. Ferromagnetic materials are attracted to an EXTERNAL magnetic field and have a net magnetic moment. But antiferromagnetic materials have a zero net magnetic moment |
