Abstract: A heat assisted magnetic recording disk drive comprises a magnetic recording media with a heat sink layer including at least a material being defined by the general structure Mn+1AXn, wherein M is a transition metal, A is an A-group element, X is C or N or a mixture of C and N, and n is a positive integer, or a material defined by the general structure Mn+1AXn, wherein M is a transition metal, X is one or both of C and N, and n is a positive integer, or a mixture of the materials being defined by the general structure Mn+1AXn and the material defined by the general structure Mn+1Xn, wherein the crystal structure of the materials is hexagonal with repeated M-X-M (quasi 2D) atomic layers. The atomic layers are stacked along the {right arrow over (c)}-axis that is oriented substantially parallel to the surface normal of the heat sink layer.

Abstract: The present invention is directed towards a tubular nanosized magnetic wire, wherein the nanosized magnetic wire comprises: a tubular magnetic shell surrounding a longitudinal axis of the wire, at least one region of the tubular magnetic shell is capable of providing a 360° magnetic domain wall, wherein the 360° magnetic domain wall is self-stabilizing and has a magnetization going from a parallel alignment to a perpendicular alignment and to a parallel alignment with regards to the wire axis. The present invention also provides a practical method capable of making a tubular nanosized magnetic wire with a self-stabilizing, 360° magnetic domain wall. The present invention also relates to the use of the tubular nanosized magnetic wire in a racetrack memory device.

Abstract: A method is proposed for opening of hollow structures made of magnetic nanoparticles. To avoid an unwanted heating, the hollow structures are opened by a strong, preferably rotating magnetic field. The method can be used, in particular, for the releasing of a diagnostic and/or therapeutic agent in a human or animal body.
