This clearly shows that Nagaoka was determined to devote himself to optical spectroscopy in order to analyze the complexity of the atomic spectra, which was later known as fine structures due to the electron spin-orbit coupling and hyperfine structures caused by the nuclear spin and shape.
To measure the effectiveness of their shielding, they employed a variety of different sensors, including a fluxgate probe, liquid-helium cooled SQUID (superconducting quantum interference device) magnetometers, mercury nuclear spin magnetometers, and cesium atomic vapor magnetometers.

Additional magnetic field pulses were used to tilt the direction of the nuclear spin and create the superposition states.
Thirty-nine minutes may not seem very long but as it only takes one-hundred-thousandth of a second to flip the nuclear spin of a phosphorus ion -- the type of operation used to run quantum calculations -- in theory over 20 million operations could be applied in the time it takes for the superposition to naturally decay by one percent," said Stephanie Simmons of Oxford University, an author of the paper in the U.
