Here, we demonstrate quantitative magnetic imaging with h-BN flakes doped with negatively charged boron-vacancy (VB-) centers throughneutron irradiation. As a proof-of-concept, we image the magnetic field produced by CrTe2 , a van der Waals ferromagnet with a Curie temperature slightly above 300 K. Compared to other quantum sensors embedded in 3D materials, the advantages of the h-BN-based magnetic sensor described in this work areits ease of use, high flexibility, and, more importantly, its ability to be placed in close proximity to a target sample. Such a sensing unit will likely find numerous applications in 2D materials research by offering a simple way to probe the physics of van der Waals heterostructures. %G English %L hal-03951311 %U https://hal.science/hal-03951311 %~ UNIV-TLSE3 %~ UGA %~ CNRS %~ INSA-TOULOUSE %~ INPG %~ NEEL %~ L2C %~ INC-CNRS %~ NEEL-MNM %~ UNIV-MONTPELLIER %~ LPCNO %~ INSA-GROUPE %~ UGA-EPE %~ ANR %~ FERMI %~ TOULOUSE-INP %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP %~ UM-2015-2021 %~ UM-EPE %~ NEEL-QUAN2M %~ ICT-CHIMIE
