Benefits of Resource Strategy for Sustainable Materials Research and Development
Christoph Helbig, Christoph Kolotzek, Andrea Thorenz +4
Material and product life cycles are based on complex value chains of technology-specific elements. Resource strategy aspects of essential and strategic raw materials have a direct…
Evidence for a Ru Kondo Lattice in LaCuRuO
Stefan Riegg, Sebastian Widmann, Betina Meir +7
Rare -electron derived heavy-fermion properties of the solid-solution series LaCuRuTiO were studied for by resistivity, susceptibility,…
On the magnetism of Ln{2/3}Cu{3}Ti{4}O{12} (Ln = lanthanide)
A. Dittl, S. Krohns, J. Sebald +7
The magnetic and thermodynamic properties of the complete LnCuTiO series were investigated. Here stands for the lanthanides La, Ce, Pr, Nd, Sm, Eu, Gd,…
Colossal dielectric constants in transition-metal oxides
P. Lunkenheimer, S. Krohns, S. Riegg +3
Many transition-metal oxides show very large ("colossal") magnitudes of the dielectric constant and thus have immense potential for applications in modern microelectronics and for…
Colossal dielectric constants: A common phenomenon in CaCu3Ti4O12 related materials
J. Sebald, S. Krohns, P. Lunkenheimer +4
In the present work we demonstrate that in addition to the well-known colossal-dielectric-constant material CaCu3Ti4O12 also various members of the series Ln2/3Cu3Ti4O12 with Ln =…
Apparent giant dielectric constants, dielectric relaxation, and ac-conductivity of hexagonal perovskites La1.2Sr2.7BO7.33 (B = Ru, Ir)
P. Lunkenheimer, T. Götzfried, R. Fichtl +5
We present a thorough dielectric investigation of the hexagonal perovskites La1.2Sr2.7IrO7.33 and La1.2Sr2.7RuO7.33 in a broad frequency and temperature range, supplemented by addi…
