โฆ Synopsis
At very low temperatures, nuclear magnetic resonance frequency decreases with decreasing temperature in an ordered magnetic medium. This phenanen on (frequency pulling) is caused by a coupled motion of the electronic magnetization and the nuclear maqnetization. Application of the NMR frequency pulling to low temperature thermometry is discuss&.
