We comprehensively determine the magnetic properties of single crystals of the isostructural series of the compounds CrI3, CrBr3 and CrCl3 to obtain a systematic overview. We find a strong anisotropy of the magnetization along different directions. A detailed analysis of the uniaxial anisotropy as a function of temperature between 5K and their respective critical magnetic ordering temperature allows us to explain the temperature evolution of the magnetization along different crystallographic axes. The in-depth understanding of the bulk magnetic properties serves as a basis for the future exploration of few- and monolayer counterparts of these crystals. Such magnetic van-der-Waals materials are extremely important for spintronic and magnetoelectronic applications [1].
