An issue of current research is the integration of microwave ferrite devices with semiconductor technologies by using vacuum deposition techniques. Thin magnetic films may be used in commercial products and they can be more easily involved in the dev

We report complex magnetic permeability or susceptibility measurements of three different laboratory-synthesised magnetic fluids. Microwave frequency range is used for the measurements. We used the reflection/transmission method in a coaxial line cel

This paper presents a dielectric and magneto-dielectric study of magnetic fluids made of three different, partially substituted, manganese ferrite particles dispersed in kerosene. Measurements were performed using a wholly automated spectrometer in t

The aim of this paper is to present the NH 2 dielectric behaviour in the primary amines for the importance it bears in the interaction of aminoacids and proteins and their influence in the electric conduction processes. For that, the dielectric prope

We present a comparison between two magneto-optical methods (dynamic and transient) used to measure Browns relaxation time in a Faradays configuration. Results obtained from these two methods for several ferrofluids are in good agreement. An applicat

A magneto-optical method, conceived in our laboratory to measure Brown's relaxation frequency of ferrofluids, is compared with Fannin's technique based on impedance measurements (slit toroid). We have developed a complete theory and an experimental s

Results of investigation concerning a new application of ferrofluids (magnetic fluids) in the doMayn of non-reciprocal X-band devices are shown. Values of ferrofluid slab position x 0 , biasing field and ferrofluid saturation magnetization are determ

A simple, fast method of characterization of anisotropic magnetic materials uses a nonreciprocal X-band rectangular cell. The material may be a solid, powder, or magnetic liquid. A network analyzer measures the scattering parameters, and an original

We present susceptibility measurements on a ferrofluid in the microwave frequency range with three different measurement cells: a coaxial line, an X-band rectangular waveguide, and an X-band slab-loaded rectangular waveguide. We use the reflection/tr
