Magnetic and structural transitions in La${}_{1-x}{A}_{1-x}$CoO${}_3$ ($A$ = Ca, Sr, and Ba)

M. Kriener, M. Braden, H. Kierspel +4

We report thermal-expansion, lattice-constant, and specific-heat data of the series La_1-xA_xCoO_3 for 0<= x <= 0.30 with A = Ca, Sr, and Ba. For the undoped compound LaCoO_3 the t…
