Weak Magnetic Fields

PS/CoPd Janus particles respond very sensitively to application of low external magnetic fields. Owing to the magnetic properties, the PS/CoPd particles may be used, for example, to sense the presence of weak magnetic fields as micro-magnetometers.

Magneto Rheological

Magneto-rheological elastomer( MR elastomer) is an emerging intelligent material made up of macromolecule polymer and magnetic particles. While a promising wide application it has in the fields of warships vibration controlling for its controllable mechanical, electrical and magnetic properties by external magnetic field, design and application of devices based on it are facing great limitations imposed by its poor performance in mechanical properties and magneto effect. Aiming at developing a practical MR elastomer, a new confecting method was proposed in this paper. Then, following this new method and using a specificly designed solidifying matrix, an amido- polyester MR elastomer was developed with its mechanical property systemically explored.

Compensation Behavior

The magnetic properties of a mixed spin-2 and spin-5 / 2 Heisenberg ferrimagnetic system on a layered honeycomb lattice are investigated theoretically by a multisublattice Green-function technique which takes into account the quantum nature of Heisenberg spins. We calculate the magnetization and the compensation temperature and transition temperature of the system in an external magnetic field and in a zero external magnetic field, and find that the transition temperature of the system increases on the effect of an external magnetic field, the compensation point disappears when the single-ion anisotropy is not large and there are two compensation points when the anisotropy is large. We also calculate the initial susceptibilities of the system.

Mendelssohn and Babbitt observed that the induction in solid and hollow tin spheres which became supraconductive in an external magnetic field did not fall quite to zero, but that part of the magnetic flux was “frozen in” at the threshold value. This behaviour could be explained by considerations based on the shape of the specimen, although it was not certain if this was the only reason for the effect. It seemed therefore that it would be of interest to investigate specimens of a shape which assured simpler conditions, such as long rods in a longitudinal field, in addition to extending the experiments to a greater number of supraconducting substances. Method The same two helium liquefiers with which the previous experiments were carried out were used again. The specimens employed were in the form of long rods attached by a short thick wire of electrolytic copper to the helium container. The wire was autogenously welded to one end of the specimen, the other end of the copper wire being soldered to the helium container. In the case of mercury the metal was contained in a test tube held independently, into which a copper wire dipped and made thermal contact. A coil one layer thick of 47 s. w. g. copper wire was wound round the middle of each specimen, the ends being connected to a ballastic galvanometer.
