NPD
Position structure from a determination at 1.5K. According to the structure determination the compound composition deviates from the nominal one, being CeRh0.2Pd0.8Sn
This commensurate magnetic structure appears below TN2=1.3K. It coexists with the incommensurate one with k=[0,0,0.4] which appears below TN1=5 K (see #1.1.143). 
Assuming equal magnetic moment values in a phase separated system the magnetic moment amounts in both phases at 0.5 K to about 1.37 Bohr magneton.
