Abstract: An electrically conductive material includes a liquid gallium alloy mixed with multiple solid particles, so as to form an electrically conductive material in which solid and liquid coexist. The electrically conductive material is disposed between and electrically connecting a first conductor and a second conductor. The first conductor is disposed on a first electronic element, and the second conductor is disposed on a second electronic element.

Abstract: The present invention discloses a discontinuous islanded ferromagnetic recording film with perpendicular magnetic anisotropy. The discontinuous islanded ferromagnetic recording film includes a substrate and a ferromagnetic layer. The ferromagnetic layer is formed on the substrate and annealed by a high-temperature vacuum annealing process. After annealing, a surface energy difference existed between the ferromagnetic layer and the substrate turns the ferromagnetic layer into well-separated and discontinuous islanded ferromagnetic particles. Each islanded ferromagnetic particle is thought of a single magnetic domain, which is beneficial to achieve a discontinuous islanded ferromagnetic recording film with perpendicular magnetic anisotropy.
