The magnetostrictive guided wave sensor with a single induced winding cannot distinguish axially symmetric from non-axially symmetric features in a pipe, because it is impossible for the sensor to detect the non-axially symmetric mode waves. When we study the effect of the change of the magnetic field in the air zone for receiving the longitudinal guided wave mode, we find that the change of th...

In this paper, using micromagnetic simulations, we investigate the stress-induced frequency tunability of double-vortex nano-oscillators comprising magnetostrictive and non-magnetostrictive ferromagnetic layers separated vertically by a non-magnetic spacer. We show that relative orientations vortex core polarities $p_{1}$ $p_{2}$ have strong impact on eigen-frequencies dynamic modes. When two v...

When the photovoltaic (PV) system suffers shading problems caused by different degrees and areas, shaded PV cells will consume electricity generate heat, corresponding bypass diode operating at a certain current conduct, special magnetic field be generated in space. In this study, magnetostrictive-based detection method device for are developed from theoretical, simulation, physical experimenta...

In this paper, we propose a model for dynamic magnetostrictive hysteresis in a thin rod actuator. We derive two equations that represent magnetic and mechanical dynamic equilibrium. Our model results from an application of the energy balance principle. It is a dynamic model as it accounts for inertial effects and mechanical dissipation as the actuator deforms, and also eddycurrent losses in the...

Multiferroic composite materials, consisting of coupled ferromagnetic and piezoelectric phases, are of great importance in the drive towards creating faster, smaller and more energy efficient devices for information and communications technologies. Such devices require thin ferromagnetic films with large magnetostriction and narrow microwave resonance linewidths. Both properties are often degra...

Single crystal specimens of Fe-17 at. % Ga were tested in tension at room temperature. Specimens with a tensile axis orientation of [110] displayed slip lines on the specimen faces corresponding to slip on the {110}with a critical resolved shear stress of 220 MPa. Yielding began at 0.3% elongation and 450 MPa. An ultimate tensile strength of 580 MPa was observed with no fracture occurring throu...

A magneto-mechano-electric generator based on a magnetostrictive metallic substrate and piezoelectric polymer is reported by Kyung Tae Kim, Kwi-Il Park, co-workers in article number 2000969. This harvests electric output signals under applied alternating-current magnetic fields, which are abundant daily life.
