Abstract
Single crystals of a metallic ferromagnet La1–xSrxCoO3+δ (x = ∼0.44) were grown from KOH melt at 773 K under H2O/O2 mixed gas flow. The grown crystals had a parallelepiped form, and their surfaces were (100) planes of the pseudocubic unit cell. The edges of the largest crystal were about 0.1 mm. The XRD and magnetic susceptibility measurements indicated that the grown crystals are highly homogeneous with respect to La/Sr contents. The magnetization versus magnetic field curve was dependent on the applied field direction to the crystallographic axis, evidencing the presence of magnetocrystalline anisotropy in La1–xSrxCoO3+δ.
