Query: Persistent antiferromagnetic order in heavily overdoped
  Ca$_{1-x}$La$_x$FeAs$_2$   In the Ca$_{1-x}$La$_x$FeAs$_2$ (112) family of pnictide superconductors, we
have investigated a highly overdoped composition (x = 0.56), prepared by
high-pressure, high-temperature synthesis. Magnetic measurements show an
antiferromagnetic transition at TN = 120K, well above the one at lower doping
(0.15 < x < 0.27). Below the onset of long-range magnetic order at TN, the
electrical resistivity is strongly reduced and is dominated by
electron-electron interactions, as evident from its temperature dependence. The
Seebeck coefficient shows a clear metallic behavior as in narrow band
conductors. The temperature dependence of the Hall coefficient and the
violation of Kohler's rule agree with the multiband character of the material.
No superconductivity was observed down to 1.8 K. The success of the
high-pressure synthesis encourages further investigations of the so far only
partially explored phase diagram in this family of Iron-based high temperature
superconductors.
