Self-Assembly of Highly Epitaxial (La,Sr)MnO3 Nanorods on (001) LaAlO3

Thin films consisting of perovskite ferromagnetic nanorod (La,Sr)MnO3 with highly epitaxial quality and well-defined nanorod separation have been synthesized with pulsed laser processing. Each nanorod has an in-plane dimension of about 20−30 nm and length equal to the thin film thickness that can va...

Summary:Thin films consisting of perovskite ferromagnetic nanorod (La,Sr)MnO3 with highly epitaxial quality and well-defined nanorod separation have been synthesized with pulsed laser processing. Each nanorod has an in-plane dimension of about 20−30 nm and length equal to the thin film thickness that can vary from tens to hundreds of nm. Magnetic property measurements revealed that the magnetizations of the as-grown films are highly dependent on the evolved self-assembled structures with strong anisotropic behavior.
