Observing zero-field spin dynamics with spin noise in a pi-pulse modulated field
arXiv:1901.00714
Abstract
Spin noise spectroscopic study of spin dynamics in a zero magnetic field is commonly frustrated by the dominating 1/f noise. We show that in a pi-pulse modulated magnetic field, spin noise spectrum centered one-half of the field modulation frequency reveals spin dynamics in zero-fields, free of any low-frequency noises.
