The parent compound LaMnO3 of the hole-doped colossal magnetoresistance materials La1-xAxMnO3 (A = Ca, Sr, Ba etc.) has attracted much interest from condensed matter scientists.... -
Phase Behaviour in Pyrazine and Tetramethylpyrazine.
Pyrazine-I is stable < 302 K, phase II exists from 302-310 K, and phase III from 310-324 K. The known phase-I forms an ordered structure. It is thought that structures of...
