Abstract
Systems and methods for a magnetometer comprise a single-isotope silicon crystal doped with impurity atoms. The Larmor precession associated with energy level transitions of the impurity atoms may be detected and used to measure an external magnetic field.
Claims20
A magnetometer, comprising:
- a single-isotope silicon crystal doped with impurity atoms, wherein a Larmor precession associated with energy level transitions of the impurity atoms is detected and used to measure an external magnetic field, and wherein the Larmor precession is detected electrically based at least in part on a photoconductivity measurement of the single-isotope silicon crystal.
A method for measuring a magnetic field, the method comprising
- applying light from one or more light sources onto a single-isotope silicon crystal to excite impurity atoms of the single-isotope silicon crystal;
- detecting a Larmor precession associated with the impurity atoms of the single-isotope silicon crystal based at least in part on energy level transitions of the impurity atoms;
- and
- calculating a magnetic field measurement based at least in part on the Larmor precession,
- wherein detecting the Larmor precession comprises detecting changes in photoconductivity of the single-isotope silicon crystal.
