The splitting of a spectrum line into several components by the application of a magnetic field.‘The Zeeman effect is the splitting of a spectral line by a magnetic field.’
- ‘Known as a Feshbach resonance, this pairing phenomenon can be externally controlled by the Zeeman effect using an applied magnetic field.’
- ‘Pauli's basic model was wrong, as it considered only orbital magnetism; spin, still undiscovered in 1920, has a major role both in ferromagnetism and in the anomalous Zeeman effect.’
Late 19th century named after Pieter Zeeman (1865–1943), Dutch physicist.
