Abstract

The M-1222 compounds are synthesized in near single phase form. These compounds crystallise in I4/mmm Tetragonal structure. None of the studied compound is superconducting but they asre weakly magnetic. This is first report on synthesis of Cr and Mn -1222 compounds. These compounds are synthesized at ultra conditions of HPHT that is the 6 Gpa and 1400 C.
