The exchange coupling between a hard magnetic layer MnBi and soft Co-Fe has been found to significantly improve the maximum energy product. In this work, spin structure of exchange-coupled MnBi:Co-Fe bilayers is experimentally investigated by X-ray circular dichroism (XMCD) polarized neutron reflectometry (PNR). We find that out-of-plane magnetization reversal process bilayer involves formation...

In this paper, a simple but effective method is proposed to generate bio-mimic wave propagating motion in magnetic soft actuator. Two examples, metachronal artificial cilia and crawling of an caterpillar, are shown as demonstrations. These kinds motions which popular natural systems also primitive creatures. the system, elastic material powder were used fabricate flexible structure. There 2 ess...

CoFe/Cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. Nanowires with 30 nm diameter and the definite lengths were obtained. The effect of CoFe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. The layers thickness was controlled t...

We review some of the significant contributions to the field of strongly correlated materials and complex magnets, arising from experiments performed at the Diamond Light Source (Harwell Science and Innovation Campus, Didcot, UK) during the first few years of operation (2007-2014). We provide a comprehensive overview of Diamond research on topological insulators, multiferroics, complex oxides a...

We describe in this Letter the first measurement of multiple islands in the core of a reversed field pinch (RFP). These islands appear with current profile modification leading to magnetic fluctuation reduction in the Madison symmetric torus RFP. Magnetic island widths decrease to an unprecedented level, reducing the overlap of adjacent islands and allowing distinct islands to appear. The struc...
