Pd-capped gasochromic metal hydrides can be used as sensing layer in fiber optic hydrogen detectors. Using a sensing layer consisting of a 50 nm thick Mg70Ti30 film capped with a 30 nm Pd catalytic layer we demonstrate a drop in reflectance by a factor of 10, at hydrogen levels d ...
MgyTi 1−y alloys with 0.50 < y < 1.00 were prepared by electron beam deposition and magnetron co-sputter deposition. The effects of the deposition technique are discussed in two ways; the metallurgy of the as-deposited films and the hydrogen storage characteristics. In spit ...
By means of high-sensitivity capacitance torque magnetometers we have measured the superconducting current js and the dynamic magnetic-moment relaxation of YBa2Cu3O7 and YBa2Cu4O8 films of typically 100 nm thickness at temperatures between 2 K and Tc in magnetic fields up to 6 T. ...
