Abstract

Magnetization curves, EPR spectra, and T1 and T2 nuclear magnetic relaxation times versus Larmor frequency have been measured for the MRI contrast agent MION-46L. The resulting data can be successfully explained by adding paramagnetic and antiferromagnetic terms to the known superparamagnetic component.
