Electron paramagnetic resonance (EPR) measurements have been made on Dy 3+ and Er 3+ in lanthanum nicotinate dihydrate (LaND) single crystals, for comparison with the information described in the previous paper about single crystals of DyND and ErND.

High-frequency EMR of metalloprotein samples offers considerable potential for providing improvements in characterization of metal centers. For those metal ions that are studied at low temperature, line widths may be frequency-dependent, depending on

We have observed a nearly fourfold increase in the electron spin resonance (ESR) signal from an ensemble of single-walled carbon nanotubes (SWCNTs) due to oxygen desorption. By performing temperature-dependent ESR spectroscopy both before and after t

We have measured temperature ($T$)- and power-dependent electron spin resonance in bulk single-wall carbon nanotubes to determine both the spin-lattice and spin-spin relaxation times, $T_1$ and $T_2$. We observe that $T_1^{-1}$ increases linearly wit
