Quantum magnetometers in the Application Laboratory at Fraunhofer IAF
Various quantum magnetometers are available—all based on diamond.
The wide-field magnetometer uses a diamond plate with a multiple nitrogen-vacancy centers. It measures magnetic fields over a large sample area in a very short time and is therefore suitable for fast measurements in industrial applications. The system can be used for the characterization and optimization of ferromagnetic materials, and is also very well suited for applications in biomedicine and medical technology. Organic samples can be examined non-destructively and with imaging.

- Resolution: ± 1 µm
- Measuring area: 40 x 40 µm2 — 1 x 1 mm2
- Measuring time: seconds to minutes
- Measuring method: ODMR, Iso‑B, Quench, pulsed
- Other: Quantitative, calibration free, fast, room temperature, no magnetic field shielding, robust
High-resolution scanning probe quantum magnetometers use diamond tips with a single nitrogen-vacancy center. This makes it possible for the first time to measure magnetic field distributions at the atomic level that are not accessible using previously available methods. For example, the current flows of micro- and nanoelectronic circuits can be displayed with high resolution, which is of great benefit for error analysis.
Technical specifications
- Sensitivity: $${1.3}-{2}\:\mu{T}\diagup\:\sqrt{Hz}$$
- Resolution: ≈ 35 nm
- Measuring area: 85 x 85 x 15 µm — 100 x 100 x 15 µm
- Measuring time: minutes to hours
- Measuring method: ODMR, Iso‑B, Quench, pulsed, AFM, MOKE
- Other: room temperature, no magnetic field shielding
Volumes of NV-doped diamond are used for laser threshold magnetometry. This is a new research approach worldwide, in which a material with an optically detectable magnetic resonance is used as a laser medium. Due to its material properties, diamond with a high density of NV centers is particularly suitable for use as a laser medium.
Theoretically, higher signals and a higher contrast can be achieved, which leads to much more precise measurement results. Fraunhofer IAF benefits from the synergy of the three core competencies of diamond growth, optoelectronics or laser technology and high-frequency electronics. The laser threshold magnetometer will be used to measure the smallest magnetic fields, such as those generated in neuronal networks or by brain waves, thus opening new doors in medical diagnostics.
Technical specifications

- Measuring time: 1 ms – 10 s
- Magnetic signal: DC – AC (~ 1 MHz, frequency selective)
- Other: Room temperature, background fields, large dynamic range
