21. This leads to the number of magnetic moments decreasing as they depend on electron spins . 22. Electron spin plays an important role in magnetism, with applications for instance in computer memories.23. Simply-stated, it involves coupling of the electron spin with the orbital angular momentum of non-circular orbits. 24. Two logical qubit directions of electron spin and nitrogen kernels spin were used, with microwave impulses. 25. The electron Zeeman interaction describes the interaction between an electron spin and the applied magnetic field. 26. These include electron spin resonance ( ESR ), superconducting junctions, and many other quantum bit implementations. 27. The electron spin g-factor is approximately two. 28. Such a device, with resistance depending on the orientation of electron spin , is called a spin valve. 29. These atoms or electrons are said to have unpaired spins that are detected in electron spin resonance. 30. George Uhlenbeck and Samuel Goudsmit one year later identified Pauli's new degree of freedom as electron spin .
