Langevin-Debye formula

Langevin-Debye formula

[länzh·van də′bī ‚fȯr·myə·lə]
(statistical mechanics)
A formula for the polarizability of a dielectric material or the paramagnetic susceptibility of a magnetic material, in which these quantities are the sum of a temperature-independent contribution and a contribution arising from the partial orientation of permanent electric or magnetic dipole moments which varies inversely with the temperature. Also known as Langevin-Debye law.
