Electron paramagnetic resonance or electron spin resonance spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear mag
Typical set-up for recording EPR spectra. The user would be seated next to the RF generator, magnet, and controls for sample temperature. Bruker ELEXSYS E500 EPR instrument from NYU.
This low-temperature ESR-STM in the Center for Quantum Nanoscience is one of the first STMs globally to measure electron spin resonance on single atoms.

In electromagnetism, the magnetic moment or magnetic dipole moment is a vector quantity which characterizes the strength and orientation of a magnet or other object or system that exerts a magnetic fi

…physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford. Every electron has a magnetic moment and spin quantum number s = 1 2 , with magnetic components m s = + 1 2 or m s = − 1 2 . In the presence of an external magnetic field with strength B…
Magnetic field lines around a "magnetostatic dipole". The magnetic dipole itself is located in the center of the figure, seen from the side, and pointing upward.
