Exchange Bias E ect in Phase Separated La_0.33Pr_0.34Ca_0.33MnO₃ Thin Films

Exchange bias e ect is observed in the phase separated La_0.33Pr_0.34Ca_0.33MnO₃ thin lms. High exchange bias eld of about 1 kOe is achieved at 4 K. The exchange bias e ect in La_0.33Pr_0.34Ca_0.33MnO₃ thin lms might originate from the intrinsic phase separation of the La_0.33Pr_0.34Ca_0.33MnO₃ or surface e ect. The dependence of exchange bias e ect on temperature, cooling eld, and thickness is also investigated. This work would open an avenue to the application in the magnetic memory devices based on the phase separated manganites.
