Abstract
The effects of high hydrostatic pressures (P) and magnetic fields (H) in a broad temperature range (T=77–325 K) on the electric resistance (R) and magnetoresistance (ΔR/R 0) was studied in laser-deposited La0.7Sr0.1Pb0.2MnO3 single crystal films on (100)-oriented SrTiO3 substrates. A maximum response to the P and H variations was observed in the temperature interval of phase transitions (T=310–325 K). A growth in the pressure P leads to an increase in both R and ΔR/R 0 values, while an increase in the magnetic field strength H is accompanied by an increase in ΔR/R 0 and a drop in the electric resistance R of the single crystal films studied.
