We have synthesized and studied monodisperse iron oxide nanoparticles of smaller than 10 nm to identify between the two spinel phases, magnetite and maghemite. It is shown that 57Fe NMR spectroscopy is a promising tool for distinguishing between the

A new electrodeless method is developed for RF dielectric constant and loss measurements. In the new method a sample coil is used instead of a conventional parallel plate capacitor sample cell. The changes in coil impedance due to the sample placed i
