  Van der Waals magnetic materials are an ideal platform to study
low-dimensional magnetism. Opposed to other members of this family, the
magnetic semiconductor CrSBr is highly resistant to degradation in air, which,
besides its exceptional optical, electronic, and magnetic properties, is the
reason the compound is receiving considerable attention at the moment. For many
years, its magnetic phase diagram seemed to be well-understood. Recently,
however, several groups observed a magnetic transition in magnetometry
measurements at temperatures of around 40 K that is not expected from
theoretical considerations, causing a debate about the intrinsic magnetic
properties of the material. In this letter, we report the absence of this
particular transition in magnetization measurements conducted on high-quality
CrSBr crystals, attesting to the extrinsic nature of the low-temperature
magnetic phase observed in other works. Our magnetometry results obtained from
large bulk crystals are in very good agreement with the magnetic phase diagram
of CrSBr previously predicted by the mean-field theory; A-type
antiferromagnetic order is the only phase observed below the N\'eel temperature
at TN = 131 K. Moreover, numerical fits based on the Curie-Weiss law confirm
that strong ferromagnetic correlations are present within individual layers
even at temperatures much larger than TN.
