Magnetic Storage

In this original work, Patrick Maletinsky et. al demonstrate the successful fabrication of an NV scanning probe carved out of bulk diamond. The first Quantilever MX prototype is used to image logical bits on a magnetic hard drive prototype from Hitachi GST, revealing out-standing spatial resolution and straightforward quantitative analysis. The results mark the true beginning of reproducible scanning NV magnetometry.

Scanning NV magnetometry reveals magnetic textures in 2D material CrBr3 in cryogenic environment

/ /
Applying scanning NV magnetometry to cryogenic temperatures allowed Professor Wrachtrup and his collaborators to reveal magnetic domains and study their dynamics in atomically thin van der Waals magnets.

Characterization of room-temperature in-plane magnetization in thin flakes of CrTe2 with a single spin magnetometer

Using Qnami QuantileverMX probes, the team led by Vincent Jacques identifies the only “van der Waals” material known to date where magnetic order occurs in a few atomic layers even at room temperature 

Spatial Resolution in Scanning NV Magnetometry – Technical Note

/ / / /
This technical note explains how spatial resolution is defined in Scanning NV Magnetometry. For a given distance d between the NV center and the scanned surface, the best achievable lateral spatial resolution is 0.86 d.
