Abstract: A magnetic field causing a difference of energy level between different spin states in the sample can be applied, a spin transition in the material can be triggered by exposing the sample to electromagnetic radiation of an energy level corresponding to the difference in energy level between the different spin states, a sensing surface of a superconducting element can be exposed to a magnetic field of the spins in the sample, the spin transition can cause, via kinetic inductance, a change in electromagnetic waves carried by the superconducting element which can be detected. A magnetic field component normal to the sensing surface, below a certain magnetic field threshold, can be applied to favor sensitivity.
