外文标题：Micron-resolved quantum precision measurement of magnetic field at the Tesla level

外文摘要：We develop a quantum precision measurement method for magnetic field at the Tesla level by utilizing a fiber diamond magnetometer.Central to our system is a micron-sized fiber diamond probe positioned on the surface of a coplanar waveg-uide made of nonmagnetic materials.Calibrated with a nuclear magnetic resonance magnetometer,this probe demonstrates a broad magnetic field range from 10 mT to 1.5 T with a nonlinear error better than 0.0028％under a standard magnetic field generator and stability better than 0.0012％at a 1.5 T magnetic field.Finally,we demonstrate quantitative mapping of the vector magnetic field on the surface of a permanent magnet using the diamond magnetometer.
