- SmBaMn$_{2}$O$_{6}$ undergoes several structural and magnetic phase transitions with changing temperature (Sagayama, 2014; Chen, 2019):
- Below 190K the structure is in a polar orthorhombic phase with space group $Pmc2_{1}$ #26.
- Between 190K and 362 K the structure is in a non-polar orthorhombic phase with space group $Pnma$ #62 (this structure).
- Above 362 K the structure is in quadrupled perovskite orthorhombic phase with space group $Cmmm$ #65.
- In the high temperature phase the samarium and barium sites may be disordered, in which case the system is in the cubic perovskite ($E2_{1}$) structure.
- Here we use the structural information from (Sagayama, 2019) at 300K. They give two possible structures: The first has the samarium atoms on the (4c) sites and barium atoms on an (8d) site. The second, shown here, has barium atoms on the (4c) sites and samarium on an (8d) site.
- (Sagayama, 2019) give the structure of this phase in the $Pnam$ setting of space group #62. We used FINDSYM to transform this into the standard $Pnma$ setting.
