    摘要: A method of generating a thin film for use in a spin valve of a magnetoresistive (MR) sensor having a nano-constricted spacer is provided. The bottom portion of the spin valve is deposited up to the pinned layer, a deposition chamber is provided, and the spacer layer is sputtered thereon. A main ion beam generates ions onto a composite surface including magnetic chips and insulator material. Simultaneously, an assisted ion beam provides ions directly to the substrate, thus improving the softness of the free layer and smoothness of the spacer layer. Neutralizers are also provided to prevent ion repulsion and improve ion beam focus. As a result, a thin film spacer can be formed, and the nano-constricted MR spin valve having low free layer coercivity and low interlayer coupling between the free layer and pinned layer is formed.

    摘要: A germanium detector measures an energy spectrum of a gamma ray flux. The detector includes a cooling layer continuous over a periphery of the columnar germanium crystal. The cooling layer reduces current leakage induced by heat, so that high energy gamma rays can be precisely detected. A combination of a plurality of germanium crystal bodies connected one another to form the germanium crystal of at least 20 cm leads to a more precise detection of high energy gamma rays. A method for determining a photonuclear reaction cross section using the germanium detector enables measurement of the energy dependence of a photonuclear reaction cross section at high resolution. The method employs a white gamma ray flux radiated to a nuclide. The germanium detector measures the spectrum of a transmission gamma ray flux transmitted through the nuclide. Peaks are specified in the obtained spectrum. An atomic nucleus can be transformed using a monochromatic gamma ray flux having an energy level corresponding to the peak.
