The accuracy of MPMS measurements depends on several critical factors, including sample geometry, mounting position and magnitude of the magnetic moment. In order to obtain the best possible results, these factors, as well as the background contribution of the sample holder have to be considered. This study investigates the advantages of using 3D printed sample holders in the context of determining the magnetic properties of Ba3CrN3Hx. Key benefits of 3D printed samples include uniform material in the holder throughout the MPMS scan range. A precisely designed sample space, printed to the exact dimensions of the sample minimises the measured background as well as axial or radial displacement errors during measurement. The sample space allows for mounting and measurement in any orientation, and measurement of reactive materials without contamination of varnish or adhesives. The airtight sample space ensures precise sealing allowing controlled mounting and measurement of air-sensitive samples. These benefits are demonstrated by precisely studying the field- and temperature-dependent magnetization of Ba3CrN3Hx (x = 0 - 0.5).
