  High-quality single crystal of Ca0.8La0.2Fe0.98Co0.02As2 has been
successfully synthesized using a self-flux method. The magnetization
measurement reveals a second peak effect and high critical current density
exceeding 2*10^6 A/cm2 at 5 K(self-field). The upper critical field anisotropy
was systematically studied by measuring the electrical resistivity under
various magnetic fields and angles. The angle dependent magnetoresistance, by
choosing an appropriate anisotropy parameter within the framework of the
anisotropic Ginzburg Landau (AGL) theory, can be scaled onto one single curve.
In the normal state, the negative Hall coefficient shows strong but
nonmonotonic T-dependence through a minimum at 175 K. Moreover, it is shown
that the magnetoresistance apparently violates the semiclassical Kohler's rule
below 175 K but can be well scaled by the Hall angle instead. This suggests
either the change of carriers with T or the exotic anisotropic scattering in
the system.
