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 ...

A new class of vibration energy harvester based on magnetostrictive material (MsM), Metglas 2605SC, is designed, developed and tested. It contains two submodules: an MsM harvesting device and an energy harvesting circuit. Compared to piezoelectric materials, the Metglas 2605SC offers advantages including higher energy conversion efficiency, longer life cycles, lack of depolarization and higher ...

Lorentz microscopy was applied to the observation of magnetic domains in iron-gallium (Fe–Ga) alloys. Results did not show any link between the magnetic domains and the magnetostriction enhancement by Ga addition, but did reveal that the drastic decrease in magnetostriction for Fe–31.2 at. % Ga was due to the presence of large scale precipitates. Magnetic domain features did not change in the a...

To progress the proficiency and broaden action bandwidth of vibration energy harvesters, this paper presents a cantilever piezoelectric-magnetostrictive bistable hybrid harvester with dynamic magnifier. The energy-harvesting system comprises two degrees freedom electrical freedom. It consists composite beam made three layers, in which magnetostrictive piezoelectric layers are attached to top bo...
