A method for determining the best fit of a complex Mossbauer spectrum is presented and applied to the room temperature 57Fe Mossbauer spectrum of HoBa2(Cu0.95Fe0.05)3O7.02. The method generates many “good fits” as do previous methods. The “best

The high- T c superconductor HoBa 2 (Cu 0.95 Fe 0.05 ) 3 O 7.02 was studied by thermogravimetry and Mossbauer spectrometry. The oxygen stoichiometry of the Mossbauer sample as determined by reduction with a mixture of nitrogen and hydrogen was 7.02±

Since their discovery in 1986 [11], the high temperature superconducting (HTS) copper oxides have presented a continuing challenge to both experiment and theory. The identification of the underlying mechanism (or mechanisms) responsible for their sup

The ${\mathit{L}}_{1,2,3}$ edges of Pr, Gd, and Ho in ${\mathrm{YBa}}_{2}$${\mathrm{Cu}}_{3}$${\mathrm{O}}_{7}$ were compared with a variety of reference compounds in an attempt to determine their valence and electronic configuration. A double-differ

Isomer shift measurements show the Eu to be trivalent and nonmagnetic with no apparent anomaly between measurements made above and below the transition temperature (Tc=87 K). The value of the isomer shift at room temperature (0.69±0.02 mm/s) falls w

In separate experiments incident pulses from two different Nd‐glass lasers and a CO2 laser were fired at planar targets of thin plastic, and the angular distributions of the soft x rays and fast electrons were measured. The focused power densities

The results of our analysis strongly support our two Fe environment hypothesis. The critical concentration at about 12 at.% suggests that the dependence of H(0,x) on x undergoes a fundamental change at this concentration. Furthermore, the so-called c

The magnetic properties of two amorphous Fe−Ni−Zr alloys, Fe89.7Ni0.03Zr10 and Fe70Ni20Zr10, both in the “as cast” and neutron irradiated states were investigated by Mossbauer spectroscopy and dc magnetic susceptibility measurements. The uppe

Enhanced diffusion in α-brass was measured during irradiation with 235U fission fragments and the results compared with previous work that used fission-reactor neutrons and 14.8 MeV neutrons. Calculations of damage energy from these three sources in
