Paper Abstract

The manipulation of magnetic anisotropy in a Co/Pt nano- multilayer(nano-ML) system with particles being embedded is reported. The samples, fabricated by a newly-developed normal incidence pulsed laser deposition (NIPLD) method, have salient magnetic properties, different from particle- free samples of almost the same structure: (1) they exhibit bi-axial magnetic anisotropies and (2) there exists a critical field at which the change in easy direction from a parallel direction to a perpendicular direction and vice versa. The careful manipulation of particles and nano- layers has also allowed us to control the degree of magnetic anisotropy by embedding particles in a well-defined nano- multilayer system: uni-axial anisotropy to bi-axial one and vice versa. This work indeed clearly shows that the integration of nano-building blocks into nano-structures can tailor properties of nano-materials.
