Outline of Final Research Achievements |
To verify “Helical Vortex state”, which is expected to appear in Type II non-centrosymmetric superconductors, we had been trying to grow high quality single crystals of LaNiC2 by floating zone method. With a crystal with optimum Tc, we performed small angle neutron scattering experiment but failed to observe magnetic Bragg reflections from flux line lattice. To bare reasons, we extended the ways and got new crystals by Czochralski and laser-FZ methods, with cooperation of RIKEN CEMS members. We checked crystal quality by EDX and found that slow growing speed like 0.3㎜/h improves the quality of the crystals. This keeps us searching optimum condition. We are planning to perform next small angle neutron scattering experiment in 2017.
