Disclosing the magnetic structure of PrBaMn2O6 and NdBaMn2O6 single crystals.
We want to determine the magnetic structure of PrBaMn2O6 and NdBaMn2O6. Both samples are perovskites with layered ordering of Pr(Nd) and Ba atoms along the c-axis. They are isostructural at high temperatures adopting a tetragonal unit cell (space group P4/mmm). They undergo magnetic transitions around room temperature and significant differences in the magnetic ground state have been found using neutron powder diffraction. A mixture of CE- and A-type magnetic structures were reported for the Pr-based compound whereas only A-type for the Nd-one. However, recent x-ray diffraction studies on single crystals of Nd-based sample reported contradictory results about a new kind of orbital ordering in the low temperature phase and the occurrence of new superstructure peaks in the low temperature phase not compatible with an A-type magnetic ordering. We have grown single crystals of both specimens with the aim of giving a definitive answer about the magnetic order developed by these compounds and the existence, or not, of a new type of orbital ordering.
