文摘

LiMn_0.95Ni_0.05PO₄ single crystals have been grown for the first time by the travelling-solvent floating-zone method at low argon pressure. The grown sample exhibits large single crystalline grains as revealed by means of polarization microscopy, X-ray Laue back scattering, and single-crystal X-ray diffraction. The composition of the crystal was determined by Energy-dispersive X-ray (EDX) spectroscopy. LiMn_0.95Ni_0.05PO₄ orders in an orthorhombic olivine-like structure as expected and phase purity was confirmed by powder X-ray diffraction. An oriented cuboid with size of 2.4脳2.5脳2.7 mm³ along a, b, and c crystalline directions, respectively, was used for anisotropic magnetic measurements.
