DiaMRI - Diamond tips as magnetic sensors

Scanning electron micrograph of a diamond tip.

The market for data storage displays an annual increase of 110 – 120%. As a result of the rapidly growing storage density, the calibration of hard disks requires new approaches such as quantum sensors. By using NV-based magnetometry with nanoscale resolution NV-based magnetometric sensors will be developed in the project DiaMRI. They can be used in research and development of hard disks and their tests in production.
