Weak static magnetic field based on scanning nitrogen-vacancy probe
Imaging measurement method
1 Scope
This paper describes a method for imaging the weak static magnetic fields generated by a sample using scanning nitrogen-vacancy probe microscopy:
This document is applicable to the use of scanning nitrogen-vacancy probe microscopy to perform magnetic induction intensity imaging on the sample surface: The specific scenarios are as follows:
---Magnetic analysis of weak magnetic samples (magnetic induction intensity typical value < 10mT) represented by magnetic films and two-dimensional magnetic materials
Imaging;
---Magnetic imaging of magnetic samples with low coercivity;
---Quantitative study of magnetic structure or magnetic moment density;
---Imaging of microscopic scale electric current and magnetic field:
Note: The nitrogen-vacancy color centers referred to in this document refer specifically to the negatively charged nitrogen-vacancy color centers in diamond:
