ferromagnetism

Examples of ferromagnetism in the following topics:

• Physical Properties and Atomic Size

  • Ferromagnetism occurs when individual atoms are paramagnetic and the spin vectors are aligned parallel to each other in a crystalline material.
  • Metallic iron is an example of a ferromagnetic material involving a transition metal.
  • Anti-ferromagnetism is another example of a magnetic property arising from a particular alignment of individual spins in the solid state.
  • Ferromagnetism is the physical theory which explains how materials become magnets.

• Transition Metals

  • Ferromagnetism occurs when individual atoms are paramagnetic and the spin vectors are aligned parallel to each other in a crystalline material.
  • Metallic iron and the alloy alnico are examples of ferromagnetic materials involving transition metals.
  • Anti-ferromagnetism is another example of a magnetic property arising from a particular alignment of individual spins in the solid state.

• Electron Configurations and Magnetic Properties of Ions

  • Permanent magnets have persistent magnetic fields caused by ferromagnetism, the strongest and most familiar type of magnetism.
  • If the spins tend to align spontaneously in the absence of a magnetic field, the resulting species is termed ferromagnetic.

• The Third Law of Thermodynamics and Absolute Energy

  • Only ferromagnetic, antiferromagnetic, and diamagnetic materials can satisfy this condition.
