Nd-Fe-B/α-Fe multi-layered nanocomposite film-magnets were prepared from a rotating Nd2.6Fe14B/α-Fe composite target by the pulse laser deposition method with a NdYAG laser (λ=355 nm). The prepared film-magnets were composed of approximately 800 layers with the thickness of about several tens nanometre, and exhibited hard magnetic properties after annealing. The laser power for the ablation of ...

Introduction: There is a need for an instrument that can be used for remote in situ identification of biogenic and a-biogenic minerals, various types of ices, organic materials etc. on planetary surfaces. The potential for measuring remoteRaman spectra of organic [1] and inorganic materials and minerals [2] with a small telescope and CW lasers have been demonstrated. Pulsed-laser Raman spectros...
