摘要: Single crystalline La0.33Pr0.34Ca0.33MnO3/MgO core-shell nanowires with diameters about tens of nanometers are synthesized by a two-step process. Structure and morphology characterizations confirm the epitaxial growth La0.33Pr0.34Ca0.33MnO3 shell layers on MgO core layers. Clear interfaces observed between Magnetic measurements suggest existence electronic phase separation in one dimensional similar to bulk. However, exhibit significantly increased amount magnetically frozen coercivity, which attributed strongly modulated magnetic structure structure.
