The titanium addition is also effective for decreasing the intermediate annealing temperature and the final heat treatment temperature. S K, Hc2 of over 22 T and an overall J c of lX104 A/cm 2 at 13 T have been obtained [3S]. The Chevrel type ternary molybdenum chalcogenides, MxM06XS (X = S, Se, Te), have a rhombohedral structure which is built up from cubic units of M06XS. The arrangement of M06XS units leaves a space between them where the Matoms are situated. The ternary Matom is Pb, Sn, Ag, Cu, Zn, Mg or rare earth elements.

The ternary Matom is Pb, Sn, Ag, Cu, Zn, Mg or rare earth elements. 13 [36]. 2K) of PbM06SS is about SO T which is the highest value reported in the superconducting materials so far. E N 50 ~ ~ w ~ 40 ~ ~ ~ U ~ 30 20 ~ ~ i 10 Upper critical field versus temperature for various high-field superconductors ~ Temperature (K) Several attempts have been made to fabricate this extremely high Hc2 compound into wires. The vapour reaction of molybdenum wire with first sulfur and then lead vapour to produce PbM06SS layer has been studied [37].

We show the result for the helical spin magnet MnSi. This shows a large negative magneto-resistance due to the spin fluctuation (Fig~12). 2 K [13J. Another Typical application is the determination of Hc2 in high Hc2 superconductors. 13 which is the champion of all these materials [14J. 12 6. 0. Constructions and applications of the spectrometer were done by MOTOKAWA of our Univ. and several interesting results are found [5J. Two important results are shown here. One of them is the discovery of the SH3 term which is an additional new term of the effective spin hamiltonian in ionic crystals.
