Claim 6:
7. A magnetic field measurement method, comprising the steps of:
(a) sensing a measurement target magnetic field at plural measurement position different from each other, and (b) applying application magnetic fields corresponding to the measurement target magnetic field sensed at the plural measurement positions to a magnetic resonance member along respective different directions corresponding to arrangement orientations of a vacancy and an impurity in a crystal lattice of the magnetic resonance member, the magnetic resonance member including a crystal structure and capable of electron spin quantum operations with microwaves of different frequencies corresponding to the arrangement orientations;
detecting physical phenomena corresponding to the application magnetic fields using the magnetic resonance member, and determining detection values of the physical phenomena corresponding to the plural measurement positions; and
calculating the measurement target magnetic field at the plural measurement positions on the basis of the detection values.
