Magnetic and magneto-transport properties of La0.69Ca0.31MnO3. (A) T-dependence of the magnetization with an Inset showing the unit cell structure as well as the crystalline axes. (B) T-dependence of the resistivity measured from a slab of a single crystal under different fields. The Inset shows a schematic arrangement of the measurements from the crystal with a slab sample size: 3.8 × 0.85 × 0.15 mm3. The sample c-axis is normal to the slab plane. (C) Angle- and T-dependences of the normalized resistivity, ρ(Θ)/ρ(Θ) = 0°, measured under a magnetic field rotating about the x-direction (i.e., the current (I) direction).
