  The magnetic and magnetotransport properties of single crystalline
La1-x-yPryCaxMnO3 (x=0.42, y=0.40) thin films (~140 nm) deposited on (110)
oriented LaAlO3 and SrTiO3 substrates exhibit a crossover from the high
temperature antiferromagnetic-charge ordered insulator (AFM-COI) phase (T>TN)
to strain glass (T<Tg). At intermediate temperatures (Tg<T<TN) dynamical liquid
having prominent thermal-magneto-resistive hysteresis dominates in the cooling
cycle, while in the warming cycle it is preceded by ferromagnetic metal (FMM)
phase. Magnetic field required to drive AFM-COI to FMM phase transition are
higher than that for the strain glass. The magneto-electric nature and
temperature span of the distinct magnetic regimes are sensitive to the thermal
cycling and substrate induced strain.
