Abstract: Multiferroic YMn2O5 fine powders were synthesized by a hydrothermal process from Y(NO3)3 · 6H2O and Mn(NO3)2, and their structure and magnetic characteristics were evaluated. YMn2O5 fine powders with orthorhombic structure were synthesized by the present process with aqueous NaOH as the mineralizer, and the synthesis conditions such as temperature and [NaOH] have significant effects upon the grain size and morphology. The single phase YMn2O5 fine powders with the most uniform morphology were synthesized at 523 K from the solution with [NaOH] = 1 M, and then the good sinterability was expected at lower temperatures where the phase separation in YMn2O5 ceramics could be avoided. YMn2O5 fine powders derived by the present hydrothermal process indicated the weak ferromagnetism below 45 K. [ABSTRACT FROM AUTHOR]
