2024-12-20 to 2025-01-02: Reduced Holiday Operations

Dear Birck Research Community,

The Purdue winter recess begins effective Friday afternoon December 20th and concludes Thursday morning, January 2. The university is officially closed during this time. As we have done in past years, the Birck Nanotechnology Center will remain available for research but will be unstaffed and hazardous gasses will be unavailable. Lab work may otherwise proceed, though any fume hood work must be done with someone else present in the same laboratory or cleanroom bay (the "buddy" system). Click the link above to get more detail about equipment conditions and rules.

Refer to the Material and Process Compatibility page for information on materials compatible with this tool.
Equipment Status: Set as UP, PROBLEM, or DOWN, and report the issue date (MM/DD) and a brief description. Italicized fields will be filled in by BNC Staff in response to issues. See Problem Reporting Guide for more info.

Note that we do not permit powders or any samples which can release material in the lab – these must be encapsulated in your lab before coming.

For MPMS magnetometry to 400 K:

for thin films perpendular to field: 5x5mm, 4x4mm; smaller is OK also but will need to be mounted to a larger non-magnetic substrate
thin films parallel to the field: 4x4mm up to 6x6mm
powders: typ. 1-10 mg can fit; please email ndilley@purdue.edu so I can provide you with parts to mount the powder in your lab before coming
crystals/bulk: smaller than 5mm on a side

For MPMS oven magnetometry up to 1000 K:

thin sample parallel to field: less than 5x5mm; recommend <0.5mm thick, otherwise we will need to use water-based cement to bond the sample to holder.
Other samples: we can discuss in training
