Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons.The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei.
Electron spin resonance dating, or ESR dating, is a technique used to date materials, for which radiocarbon dating does not work well, such as minerals (e.g. carbonates, silicates, sulphates), inorganic biological materials (e.g., tooth enamel), inorganic archaeological materials (e.g., ceramics) and certain foods.

Pulsed electron paramagnetic resonance (EPR) is an electron paramagnetic resonance technique that involves the alignment of the net magnetization vector of the electron spins in a constant magnetic field.
In physics, biology and chemistry, electron magnetic resonance (EMR) is an interdisciplinary field that covers both electron paramagnetic resonance (EPR, also known as electron spin resonance – ESR) and electron cyclotron resonance (ECR). [1]
Electric dipole spin resonance (EDSR) is a method to control the magnetic moments inside a material using quantum mechanical effects like the spin–orbit interaction. Mainly, EDSR allows to flip the orientation of the magnetic moments through the use of electromagnetic radiation at resonant frequencies.
Electron spin plays an important role in magnetism, with applications for instance in computer memories. The manipulation of nuclear spin by radio-frequency waves (nuclear magnetic resonance) is important in chemical spectroscopy and medical imaging.
Ferromagnetic resonance is a convenient laboratory method for determining the effect of magnetocrystalline anisotropy on the dispersion of spin waves. One group at the Max Planck Institute of Microstructure Physics in Halle, Germany proved that by using spin polarized electron energy loss spectroscopy (SPEELS), very high energy surface magnons ...
