Glass-like kinetic arrest of first-order structural phase transition in LaxMnO3{\pm}δ (x= 1 & 0.9)

Aga Shahee, Dhirendra Kumar, N. P. Lalla

We report here the occurrence of glass-like kinetic-arrest of first-order phase transition of R-3c to Pbnm in a supercooled LaxMnO3\pmδ (X= 1 & 0.9 and δ>0.125) below its insulator…
