" 2D materials' weak interlayer bonds allow low thermal conductivity/ high anisotropic heat dissipation... controlling heat flow/ magnetic properties on timescales as short as 100's of fs... specific wavelength laser pulses heat material, then pulses at another wavelength probe resulting changes for real-time temperature/ magnetization monitoring, enabling sub-ps temporal resolution/ sub-µm spatial resolution... manipulate magnetic layers' thickness enhancing heat dissipation/ accelerating magnetization recovery"
