Rare earth substitution in lattice-tuned Sr<sub>0.3</sub>Ca<sub>0.7</sub>Fe<sub>2</sub>As<sub>2</sub>solid solutions
Rare earth substitution in lattice-tuned Sr<sub>0.3</sub>Ca<sub>0.7</sub>Fe<sub>2</sub>As<sub>2</sub>solid solutions
The effects of aliovalent rare earth substitution on the physical properties of Sr0.3Ca0.7Fe2As2 solid solutions are explored. Electrical transport, magnetic susceptibility and structural characterization data as a function of La substitution into (Sr_1-y_Ca_y)_1-x_La_x_Fe2As2 single crystals confirm the ability to suppress the antiferromagnetic ordering temperature from 200 K in the undoped …
