Study Notes
Magnetic Materials
- Diamagnetic materials are repelled by magnets and exhibit a weak magnetic response.
- Ferromagnetic materials are strongly attracted to magnets and can retain their magnetization even after the external magnetic field has been removed.
- Ferrimagnetic materials exhibit spontaneous magnetization, similar to ferromagnetic materials, but with a weaker magnetic response.
Key Differences
- Diamagnetic materials vs. Paramagnetic materials: Diamagnetic materials are repelled by magnets, while Paramagnetic materials are weakly attracted to magnets.
- Ferromagnetic materials vs. Ferrimagnetic materials: Ferromagnetic materials have a stronger magnetic response and can retain magnetization, while Ferrimagnetic materials have a weaker magnetic response.
Antiferromagnetic Behavior
- Antiferromagnetic behavior occurs when adjacent atoms or molecules have opposing magnetic moments, resulting in a net zero magnetic field.
