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...

To reach high gradients in pulsed operation of superconducting (SC) cavities an active Lorentz force detuning compensation system is needed. For this system a piezoelement can be used as an actuator (other option is a magnetostrictive device). To guarantee the demanded lifetime of the active element, the proper preload force adjustment is necessary. To determine this parameter an absolute force...

original article background and objectives: one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf- magnetic field (mf) in substations, power plants, cities, near high voltage power lines and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf mete...

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.

We describe the use of parametric amplification to substantially increase the magnetoelectric (ME) coefficient of multiferroic cantilevers. Parametric amplification has been widely used in sensors and actuators based on optical, electronic, and mechanical resonators to increase transducer gain. In our system, a microfabricated mechanical cantilever with a magnetostrictive layer is driven at its...
