We demonstrate room-temperature ferromagnetism with in-plane magnetic anisotropy in thin flakes of the CrTe$_2$ van der Waals ferromagnet. Using quantitative magnetic imaging with a single spin magnetometer based on a nitrogen-vacancy defect in diamond, we infer a room-temperature in-plane magnetization in the range of $M\sim 25$ kA/m for flakes with thicknesses down to $20$ nm. These results make CrTe$_2$ a unique system in the growing family of van der Waals ferromagnets, because it is the…
