At low temperatures, this quantity's temperature dependence equals the product of its value at absolute zero times 1 minus the ratio of the actual and critical temperatures raised to the three halves power. The anisotropy energy of a uniaxial crystal
At low temperatures, this quantity's temperature dependence equals the product of its value at absolute zero times 1 minus the ratio of the actual and critical temperatures raised to the three halves power. The anisotropy energy of a uniaxial crystal is proportional to the square of the sine of the angle between the crystal's ";easy axis"; and this quantity. This quantity's time derivative is expressed as the sum of a torque-dependent damping term and a term proportional to this quantity's cross product with the effective field according to the Landau-Lifshitz-Gilbert equation. This quantity's curl equals the bound current density. The B-field equals the permeability of free space times the sum of the H-field and this quantity. For 10 points, namethis magnetic analogue of electric polarization density, which gives the magnetic moment of a material per unit volume.
