Magneto-sensitive

If a wire is broken, a leakage of the magnetic flow arises. The leakage can be detected by a magneto sensitive sensor, e.g. by a Hall generator, as an electric pulse while a rope moves near the sensor. Of course, the pulses from inner broken wires are less and longer than from outer ones. 

Evidence for hydrogen plasma neutralization of shallow donors in high purity (about 5 x 1014 cm-3) n-type GaAs epitaxial layers has been obtained by Pan et al. (1987a) from the observation of the discrete magneto-PTIS spectrum of the donors near 5 meV. This technique is very sensitive and it allowed to observe a decrease (between 10 and 50 percent) of the net... 

When determining the degree of branching of hydrocarbon mixtures by means of physical constants, especially those physical constants or functions thereof should be chosen that show the necessary sensitivity to the presence of branchings. Particularly the parachor and the magneto-optical rotation have found application. 

Optical rotatory dispersion and circular dichroism (83, 84) can often be of great value, and the spectra are particularly sensitive to the conformation of the protein. Much work remains to be done in this field before the results can be definitely interpreted in terms of the electronic structure of the metal. Magneto-optical rotation and magnetic circular dichroism (MOR and MCD), which are beginning to be applied to porphyrins and haemoproteins, offer much greater promise (30, 85). 

Composites with filler concentrations close to the percolation threshold exhibit conductivity which is sensitive to compressive deformation, since this brings the metal particles into contact, thereby forming percolation pathways. This sensitivity has been exploited especially in anisotropic composites. These are made by prealigning the metal particles with either electric or magnetic fields. This alignment is identical with that produced by external fields in electro- and magneto-rheological fluids where at a critical field continuous threads of...

Magneto-optical disks (MODs) are rewritable, and operate differently than either ROM or WORM disks. Data is not recorded as distortions of a thermally sensitive layer within the disk. Rather, it is written using combined magnetic and optical techniques. Digital data consisting of Is and Os is encoded in the optical signal from the laser in the usual manner. Unlike the ROM or WORM disks, however, the MOD write layer is magnetically sensitive.
