Abstract: A large-size wind power blade with a multi-beam structure and its manufacturing method, wherein the blade adopts a hollow layout structure and comprises a blade skin suction edge, a blade skin pressure edge, a main load-carrying structure crossbeam and anti-shearing webs, wherein the blade skin suction edge and the blade skin pressure edge are combined to form a cavity structure having a streamlined cross section, wherein a support structure formed by the combination of the main load-carrying structure crossbeam and the anti-shearing web is located in the cavity. Both the blade skin suction edge and the blade skin pressure edge adopt a multi-segment combined structure, wherein the multiple segments are connected to the side surface of the main load-carrying structure crossbeam to integrally form the blade skin suction edge and the skin pressure edge.

Abstract: A magnetic tunnel junction having a ferromagnetic free layer and a ferromagnetic pinned reference layer, each having an out-of-plane magnetic anisotropy and an out-of-plane magnetization orientation, the ferromagnetic free layer switchable by spin torque. The magnetic tunnel junction includes a ferromagnetic assist layer proximate the free layer, the assist layer having a low magnetic anisotropy less than 700 Oe and positioned to apply a magnetic field on the free layer.
