Abstract
We report for the first time electron paramagnetic resonance linewidth measurements in an ionic water-based ferrofluid. The linewidth broade ning is studied as a function of the particle-particle distance. We ch ange the average particle-particle distance from 20 to 89 nm by diluti ng a concentrated sample with water. Magnetic and electric interaction s between adjacent particles are used to explain the experimental data .
