| Research Abstract |
We have developed a rapid and highly-efficient nanomaterial production system by using ultrashort pulse laser induced plasma inside a flow reactor made of glass. The permanent magnet nanoparticles such as Nd_2Fe_<14>B, Sm_2Fe_<17>N_3, and FePt, which are smaller than a theoretical single magnetic domain size, were successfully produced by using this system. Beyond the basic understanding, we anticipate that our system will open new opportunities in nanomaterial fabrication, material processing, optical trapping, and bio-medical ferrofluids.
