Electron Paramagnetic Resonance (EPR)
Electron paramagnetic resonance (EPR), also commonly named electron spin resonance (ESR), is a powerful spectroscopic tool in experimental condensed matter physics. With this technique one can selectively tune different electron spin ensembles into resonance by exposing the substance to high frequency electromagnetic radiation in the presence of magnetic field. EPR yields valuable information about crystal fields, spin-orbit and spin-spin interactions, spin- and lattice dynamics, spin structures and low-energy excitations in magnetically ordered states.
In our group we have built up a modern instrumentation which enables to study EPR in various kind of materials in a broad frequency-, magnetic field- and temperature range. Currently we focus our research activity on investigations of low-dimensional quantum spin magnets, molecular magnets, nano-structured materials, heavy fermion compounds, unconventional superconductors and other substances with strong electronic correlations.
