DESCRIPTION:The highest known superconducting transition temperatures at a
 mbient pressure are found in the cuprates\, layered ceramic oxides contain
 ing CuO2 planes which host charge carriers (electrons or holes\, depending
  on the other elements in the material). This seminar focuses on materials
  containing an anti-cuprate layer\, “M2O” where M is a 3d transition m
 etal\; the metal and oxygen positions are reversed with respect to the cup
 rates [1]. I will survey the literature and describe the experimental evid
 ence for magnetism and superconductivity in these compounds. I will then r
 eport our recent results in this area including the synthesis of thirteen 
 new ceramic oxide-chalcogenides and a van der Waals layered oxide-tellurid
 e [2]. We used low-temperature “soft chemistry” to manipulate the mate
 rials without destroying the structure of the layers and to synthesise new
  metastable lithium-containing phases. \n\n[1] P. Doan\, M. Gooch\, Z. Tan
