A strongly anisotropic ferromagnetic phase is identified in the ferromagnetic insulating regime. The magnetic anisotropy evolves from positive uniaxial at x=0.125 and 0.15 to negative cubiclike at x=0.175 with increasing magnitude, whereas it decreases appreciably at x=0.19, which is close to the ferromagnetic metallic phase boundary. Minor contributions from ferromagnetic inhomogeneities characterized by weaker magnetic anisotropy are traced at low temperatures for x=0.125 and 0.15, while their temperature dependence implies coupling with the major anisotropic phase. A growing tendency towards the formation of spatially separate ferromagnetic regions in the paramagnetic regime is observed at x≥0.175, as the ferromagnetic metallic phase is approached. Persistent anomalies in the temperature dependence of the FMR parameters are traced concurrently with the structural transformation at 60-70 K. © 2006 The American Physical Society.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 15</style></notes></record></records></xml>
