Аннотация: Structure and magnetic properties of Pb-3(Mn1-xFex)(7)O-15 single crystals with x=0-0.2 grown by spontaneous crystallization from solution in melt have been investigated. All the crystals belong to the hexagonal space group P6(3)/mcm. The magnetic properties appeared to be strongly dependent on the iron doping level. At small (x=0.05) dopant concentrations, the value of magnetization and Neel temperature T-N decrease insignificantly (T-N=70 K). With increasing x, the three-dimensional magnetic ordering does not occur and temperature dependences of magnetization at x >= 0.1 exhibit spin-glass-like features in the low-temperature region.
