Permalloy Ni/Fe/Mo/Mn Evaporation Pieces 1-3 mm ATOMFAIR®

This alloy evaporation material requires water-cooled e-beam hearth with Al2O3 or graphite liner for optimal deposition performance. Thermal or resistive evaporation using W or Ta boats is possible only by RFQ confirmation.

• Evaporation Source Compatibility: Confirm deposition source geometry and liner material before ordering to ensure compatibility with the water-cooled e-beam hearth or alternative boat configuration.
• Process Route Matching: Match the evaporation method to the material's melting point of 1,395 °C and density of 8.7 g/cm³ to avoid incomplete evaporation or source damage.
• Z-Ratio Consideration: Account for the Z-ratio of 1.00 when calibrating film thickness monitors for reproducible deposition rates.

This procedure covers loading and initial setup of Permalloy pieces in a water-cooled e-beam hearth. Verify source geometry and liner material before proceeding.

Required Equipment: Water-cooled e-beam hearth with Al2O3 or graphite liner, Vacuum deposition system

1. Inspect the evaporation source
   Inspect the water-cooled e-beam hearth and confirm the Al2O3 or graphite liner is clean and free of cracks.
2. Load the Permalloy pieces
   Load the Permalloy pieces (1-3 mm) evenly into the liner to ensure uniform heating and avoid spitting.
3. Set the deposition parameters
   Set the e-beam power to achieve a controlled ramp rate, monitoring the melt pool to prevent thermal shock.
4. Verify the vacuum level
   Verify the chamber pressure is below 5×10⁻⁶ Torr before initiating evaporation to minimize contamination.
5. Begin the deposition process
   Begin the deposition at a rate consistent with the target film thickness, using the Z-ratio of 1.00 for crystal monitor calibration.

This Permalloy (Ni/Fe/Mo/Mn) evaporation material in 1-3 mm pieces is optimized for e-beam evaporation using a water-cooled hearth with Al2O3/graphite liner, offering good performance for thin-film deposition, though thermal/resistive evaporation requires RFQ confirmation and the composition is specified by RFQ rather than a fixed standard.

Positive

• E-beam evaporation compatibility: The material is rated 'Good' for e-beam evaporation using a water-cooled e-beam hearth with Al2O3/graphite liner, a common configuration in research deposition systems, ensuring reliable film formation.
• Defined physical form for loading: Supplied as 1-3 mm pieces, this form factor facilitates consistent source loading and controlled evaporation rates in vacuum deposition workflows.

Trade-offs

• Composition by RFQ only: The exact Ni/Fe/Mo/Mn composition is not fixed and must be specified by RFQ, requiring additional procurement coordination and potentially delaying delivery if standard grades are not suitable.
• Thermal evaporation requires RFQ: Thermal or resistive evaporation is not directly supported and requires RFQ confirmation, limiting immediate deployment in systems without e-beam capability.
