  Influence of permanent magnetic field up to 7.5 T on plasma emission and
laser-assisted Au nanoparticles fragmentation in water is experimentally
studied. It is found that presence of magnetic field causes the breakdown
plasma emission to start earlier regarding to laser pulse. Field presence also
accelerates the fragmentation of nanoparticles down to a few nanometers.
Dependence of Au NPs fragmentation rate in water on magnetic field intensity is
investigated. The results are discussed on the basis of laser-induced plasma
interaction with magnetic field.
