Implication

Theoretical analysis reveals core polarization significantly influences nuclear relaxation rates in transition metals, indicating multiple electron interactions govern magnetic behavior.

Key Points

To calculate nuclear spin relaxation induced by core polarization in transition metals within the tight-binding approximation and evaluate its contribution alongside other electronic mechanisms.
Derived theoretical relations between core polarization Knight shift and relaxation rates using a tight-binding framework.
Calculated relaxation contributions from contact, core polarization, and orbital interactions across three transition metals using estimated hyperfine fields.
Established a Korringa-like relation for core polarization featuring an inhibition factor governed by the relative weights of orbital symmetries at the Fermi surface.
Demonstrated that contact, core polarization, and orbital mechanisms all provide significant contributions, yielding satisfactory agreement with experimentally observed relaxation rates.
