✦ Synopsis

The cubic-to-tetragonal martensitic transformation temperature Tm(H ) under magnetic fields H in Nb3Sn is investigated by detecting the electrical resistance anomaly associated with the transformation. Fields up to 12 T are applied along [l 10] of the single crystal with RR= 8, T c = 18.2K and Tin(0 ) = 38.8K. T,,(H) decreases by 0.3 K at H= 12T and its field dependence is found to be [Tm(H ) -Tm(O)]/Tm(O ) =-(0.17-+ O.03) [l~BH/ke. Tm(O)] 2. This is analyzed successfully by using the F~2 subband model. Discussions are also given focusing on the comparison with V3Si.

THE author has recorded the decrease of a field trapped in a Nb3Sn hollow cylinder with increasing temperature, and found the trapped field to be approximately proportional to (1 -T/Te). In the range of field strength examined, the relation ~z = J~(H + Bo) was followed approximately; the resulting q
