The Deutsches Elektronen-Synchrotron , commonly abbreviated DESY, is a national research center in Germany that operates particle accelerators used to investigate the structure of matter. It conducts a broad spectrum of inter-disciplinary scientific research in three main areas: particle and high energy physics; photon science; and the development, construction and operation of particle accelerators. DESY is publicly financed by the Federal Republic of Germany, the States of Germany, and the German Research Foundation . DESY is a member of the Helmholtz Association and operates at sites in Hamburg and Zeuthen. Wikipedia.

A method of producing a multilayer magnetoelectronic device and a related device. The method includes depositing a multilayer structure including at least two ferromagnetic layers disposed one on top of the other and each having a magnetic anisotropy with a corresponding magnetic moment. A magnetization curve is specified for the magnetoelectronic device. The number of ferromagnetic layers and, for each of the ferromagnetic layers, the magnetic moment and the magnetic hardness for obtaining the specified magnetization curve are determined. For each of the ferromagnetic layers a magnetic material, a thickness, an azimuthal angle and an angle of incidence are determined for obtaining the determined magnetic moment and magnetic hardness of the respective ferromagnetic layer. The multilayer structure is deposited using the determined material, thickness, azimuthal angle and angle of incidence for each of the ferromagnetic layers.

The present invention is directed to a chirped dichroic mirror comprising a stack of alternating high refractive index and low refractive index layers, a front end portion including an antireflective coating followed by an impedance matching region in which the ratio of the optical thickness of a high refractive index layer to the optical thickness of the next following low refractive index layer is adiabatically increasing to a first value, the impedance matching region being followed by a chirped mirror region where the Bragg wavelength of the layer pair is generally increasing or generally decreasing, characterized in that the layers in a back end region form a second impedance matching region in which the ratio of the optical thickness of a high refractive index layer to the optical thickness of the next following low refractive index layer starts at the value of this ratio in the adjacent chirped mirror region and is then adiabatically decreasing in order to provide matched impedance to the surrounding medium over the transmission spectral band.
