For First-time Users
About the High Magnetic Field Characterization Unit
The High Magnetic Field Characterization Unit supports a wide range of physical property measurements, including electrical, magnetic, optical measurements and high-field NMR using superconducting and other high-field magnets. We provide an environment for advanced characterization of semiconductors, magnetic materials, superconductors, nanomaterials, quantum materials, battery and catalytic materials, enabling access to local structures, electronic states, and physical properties that are difficult to obtain using conventional techniques.
Overview of the Usage Flow
1. Pre-use Consultation
Based on the measurement objectives and sample information, staff will assess feasibility. Consultation is welcome even if you are unsure which instrument to use or whether measurement is possible.
2. Selection of Usage Category
External users (universities/companies) and internal NIMS users follow different procedures, documentation, and fee schemes. An appropriate usage option will be proposed based on your consultation.
3. Application
Once the usage category is determined, please check the application procedures and required documents via the relevant pages (External Users / NIMS Users).
4. Approval and Scheduling
After review and approval of the application, the measurement schedule will be finalized.
5. Measurement
Choose from self-operation, technical assistance, or staff-operated measurements. Operation training may be required. Staff will support safe operation under high magnetic field conditions.
6. Data Delivery and Use of Results
Measurement data will be provided after completion. When publishing results, acknowledgment of facility use is requested (requirements depend on the usage category).
Information to Be Prepared in Advance
- Sample details
(composition, shape, size, safety considerations)
- Measurement objectives
(e.g., electrical transport, magnetization, high-field NMR)
- Desired measurement conditions
(magnetic field range, temperature range, orientation)
- Reference publications or data
(if available)
- Preferred measurement mode
(self-operation / technical assistance / staff-operated)
Notes on Using High Magnetic Field Environments
Measurements in high magnetic field environments have characteristics that differ from those of conventional analytical instruments.
-
Measurements may be limited due to physical effects such as magnetic forces or sample heating; prior discussion with staff is required.
-
When cryogens such as liquid helium are involved, follow staff instructions.
- Operation training or staff supervision may be required to ensure safe use.
