Coherent terahertz emission from ferromagnetic films excited by femtosecond laser pulses
Eric Beaurepaire,Gordon M. Turner,Shayne M. Harrel,Matthew C. Beard,Jean-Yves Bigot,Charles A. Schmuttenmaer +5 more
TL;DR: In this paper, it was shown that the laser induced ultrafast demagnetization of ferromagnetic films results in the emission of a terahertz electromagnetic pulse, which was detected from Ni films using free-space electro-optic sampling.
Journal ArticleDOI
The physics and applications of ion beam erosion
TL;DR: In this article, a review summarizes current understanding of the sputtering process and the origin of the above dependences and describes how, if only a surface gradient related mechanism dominates, the evolution of surface geometry can be accurately predicted.
