The magnetoelectric response of magnetostrictive/piezoelectric laminate composites has been investigated. Based on the piezoelectric and piezomagnetic constitutive equations, and motion equation for the composite plate, the magnetoelectric equivalent circuit has been derived, and the magnetoelectric coefficients predicted. Prototype devices of, as an application example, Terfenol-D/PZT composit...

A compact time digitizer containing 128 words of 16 bits each on a single width CAMAC module is described. Eight data channels are provided with a capacity of 16 words each. The unit has been used with a 50-MHz clock to encode data from magnetostrictive spark chambers and--with modifications--for the accumulation of data from multiwire proportional chambers. * Work supported by the Energy Resea...

This paper presents recent development on magnetostrictive linear position sensors (MLPS). A new compensation coil structure improves the EMI suppression and accuracy considerably. Furthermore, experimental results indicate that the new structure can improve the accuracy to ± 0.13 mm nearly double the ± 0.2 mm obtained with traditional structures. As another design continuation after the differ...

Electric-field control of magnetism via an inverse magnetostrictive effect is alternative path toward improving energy-efficient storage and sensing devices based on a giant magnetoresistance effect. In this Letter, we report lateral electric-field driven strain-mediated modulation magnetotransport properties in Co/Cu/Py pseudo spin valve grown ferroelectric 0.7Pb[Mg 1/3 Nb 2/3 )]O 3 –0.3PbTiO ...

In recent years, ultrasonic machining has been developing rapidly, and it is used in areas such as abrasive machining, cleaning, welding. this research, a magnetostrictive device with pure nickel conical core cone angle of 30° was constructed. The observed sound pressure level measure transducer performance. Also, the ability to reduce residual pesticide on cucumber surface due cavitation evalu...
