Abstract Materials with low thermal conductivity usually have complex crystal structures. Herein we experimentally find that a simple crystal structure material AgTlI2 (I4/mcm) owns an extremely low thermal conductivity of 0.25 W/mK at room temperatu

The realization of oxygen over stoichiometry through oxidation of Co2+ into Co3+ in the 2H-perovskite related oxides Sr1+x(Mn1−xCox)O3 is demonstrated, leading to a large family of cation deficient Ising chain oxides Sr1+y[(Mn1−xCox)1−z□z]O3.
