Previously known graphitic structures of conical shape – whiskers and helical cones – consist of a single wrapped graphene sheet, which gives a rather amorphous tip structure. Carbon nanocones, on the other hand, are nearly perfect sheets, curved

Magnetism encompasses a wide range of systems and physical phenomena, and its study has posed and exposed both important fundamental problems and many practical applications. Recently, several entirely new phenomena have thus been discovered, generat

Many mesoscopic systems display `adaptive'behaviour - changes in some physical property that results from a small change in an internal or external driving force. There is a kind of progression in adaptive phenomena, from quantum mesoscopics to compl

The motion of small nonmagnetic spheres confined in thin layers of ferrofluid subjected to a rotating magnetic field has been studied. No translational motion of the spheres was observed, but the rotating field induced a rotation of the spheres with

Polystyrene spheres of the same size (10–100μm) dispersed in ferrofluid produce voids, which have been denoted magnetic holes. A two-dimensional system of interacting magnetic holes confined between two glass plates and subject to rotating magneti

The dispersion of non-magnetic spheres in a ferrofluid results in the formation of holes with an apparent induced diamagnetic moment, which we refer to as `Superdiamagnetism'. This effect is demonstrated by means of comparison of the results of AC su
