Heavy-Fermion Formation at the Metal-to-Insulator Transition in Gd${}_{1-x}$Sr${}_x$TiO${}_3$

M. Heinrich, H. -A. Krug von Nidda, V. Fritsch +1

The perovskite-like transition-metal oxide Gd${}_{1-x}$Sr${}_x$TiO${}_3$ is investigated by measurements of resistivity, specific-heat, and electron paramagnetic resonance (EPR). Approac…
