The magnetic moment of a system measures the strength and the direction of its magnetism. The term itself usually refers to the magnetic dipole moment. Anything that is magnetic, like a bar magnet or a loop of electric current, has a magnetic moment. A magnetic moment is a vector quantity, with a magnitude and a direction.

tangent to the straight line m at the origin; this temperature marks the onset of ferromagnetism. The curve for t = 0.5 is in the ferromagnetic region and intersects the straight line m at about m = 0.94NµB,. As t → 0 the intercept moves up to m = 1, so that all magnetic moments are lined up at absolute zero.

The hard magnetic properties of Fe 3 Se 4 nanostructures were studied both experimentally and theoretically. Magnetic measurements showed that Fe 3 Se 4 nanoparticles can exhibit giant coercivity exceeding 40 kOe at low temperature (10 K). This unusually large coercivity is attributed to the uniaxial magnetocrystalline anisotropy of …

The changes seen in the second (Li to Ne), fourth (K to Kr), fifth (Rb to Xe), and sixth (Cs to Rn) rows of the s and p blocks follow a pattern similar to the pattern described for the third row of the periodic table. The transition metals are included in the fourth, fifth, and sixth rows, however, and the lanthanides are included in the sixth row.

A magnetic moment is a vector quantity, with a magnitude and a direction. An electron has an electron magnetic dipole moment, generated by the electron's intrinsic spin property, making it an electric charge in motion. There are many different magnetic forms: including paramagnetism, and diamagnetism, ferromagnetism, and anti-ferromagnetism.
