Magnetization by Laser Pulse: A Futuristic Twist in Material Science

If a strong laser pulse hits an iron alloy, the material melts briefly at the irradiated point and a tiny magnetic location kinds. When the HZDR team irradiated a thin layer of an iron-aluminum alloy with ultrashort laser pulses, the non-magnetic material suddenly became magnetic.” First, we irradiate the alloy with a strong laser pulse, which allures the material,” describes Theo Pflug.

There is a much more unusual method: A group led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) found some time ago that a certain iron alloy can be allured with ultrashort laser pulses. When the HZDR group irradiated a thin layer of an iron-aluminum alloy with ultrashort laser pulses, the non-magnetic material all of a sudden ended up being magnetic.” First, we irradiate the alloy with a strong laser pulse, which magnetizes the product,” describes Theo Pflug.
