摘要:
A double Dewar attachment has been designed for use with a Norelco x‐ray diffractometer. Operating temperatures are the points fixed by the coolant used or by pumping on the inner Dewar, although data can also be taken on a warming cycle. Experiments on Mn3O4at liquid helium temperature give no evidence for a crystal structure change associated with the ferrimagnetic transition at 43°K.
