Influence of Alternating Magnetic Fields on Zn-67 Moessbauer Resonance in ZnO

摘要

A phase-modulation theory was developed to describe the influence of alternating magnetic fields on the Mossbauer resonance of (67)Zn in ZnO. Results of the low- and high-frequency Zeeman scanning experiments were in accordance with the theoretical predictions. The transient oscillations observed were used to evaluate the amplitude of phase modulation and the gyromagnetic ratio of the 93-keV state of (67)Zn. The advantages of the time-domain approach combined with the use of the high-resolution resonance of (67)Zn were discussed.
