Magnetotactic bacteria are aqueous microorganisms that navigate in the Earth magnetic field using their internal chain of magnetic nanoparticles, which actuate as a compass needle. A typical specimen of the species Magnetospirillum gryphiswaldense co

Experimental data on and model representations of the physical processes in small detectors operating on the basis of the magnetoimpedance effect are analyzed and generalized for conditions adapted to systems of magnetic nondestructive testing. The p

Longitudinal and transverse magnetoimpedance is studied for Fe19Ni81 (150 nm)/Cu(500 nm)/Fe19Ni81 (150 nm) multilayered structures with exactly the same geometry, having either longitudinal or transverse magnetic anisotropy, at frequencies up to 500

Giant magneto-impedance has shown large sensitivities that are of great interest in practical applications. Above certain frequencies the ferromagnetic resonance controls the magneto-impedance behavior, and the resonance width limits the maximum achi

Giant magnetoimpedance (GMI) effect in NiFe (150 nm)/Cu (500 nm)/NiFe (150 nm) multilayers with longitudinal and transverse induced magnetic anisotropy was studied at frequencies of 300 kHz–3 GHz. Several sensitive elements were built in a single

The impedance values of magnetic thin films and magnetic/conductor/magnetic sandwiched structures with different widths are computed using the finite element method (FEM). The giant magneto-impedance (GMI) is calculated from the difference of the imp

In this paper we investigate different aspects of the high-frequency magnetoimpedance at low fields. In the first place, we will study this effect from a phenomenological point of view, comparing it with the low-frequency microwave absorption. The re
