← ScienceWhich outcome occurs when applying a strong external magnetic field to a material exhibiting Kondo effect?
A)Suppression of the Kondo resonance✓
B)Enhancement of spin-orbit coupling
C)Formation of Cooper pairs
D)Increased electron-phonon scattering
💡 Explanation
When a strong external magnetic field is applied, Zeeman splitting occurs because the magnetic field aligns the impurity spin, disrupting the formation of the Kondo singlet state between the impurity and conduction electrons, thus suppressing that resonance. Therefore suppression occurs, rather than other effects that require different mechanisms.
