Observation of Thermomagnetically Recorded Magnetic Domains in TbFeCo Films with Soft X-Ray Microscopy
We observed thermomagnetically recorded domains of various sizes with magnetic transmission X-ray microscopy (M-TXM) in order to clarify the recording characteristics. The domains were recorded on TbFeCo films by laser-pumped magnetic field modulation (LP-MFM) using a 635 nm laser diode. Typical ima...
