  We synthesized large superconducting single crystal Ca0.77La0.18Fe0.90As2
('112' type) of 2 millimeter size. Scanning electron microscopy (SEM)
measurements revealed that bright and dark stripes alternately spread on the
surface of crystals, indicating possible existence of intrinsic phase
separation. Temperature (T) -dependent resistivity, Hall effect and
magneto-resistance (MR) were measured with magnetic field (H) applied to
different directions of crystal. The upper critical field (Hc2) anisotropy was
estimated with a moderate value around 2.8. Positive Hall coefficient (RH) and
anisotropic MR were found and showed strong T-dependent feature. Below T about
100 K, abnormal behaviors appear simultaneously in resistivity derivative, Hall
coefficient and MR, which indicates that other scattering mechanisms more than
conventional multiband effect may exist.
