Small Impurity-Pinned Solitons in Layered Antiferromagnets
Autor: John E. Drumheller, C. E. Zaspel, Kala Subbaraman
Publikováno v: physica status solidi (a). 189:1029-1033
Layered manganese-halide compounds exhibit quasi-two-dimensional magnetic behavior in the temperature region immediately above the ordering temperature where soliton excitation can be experimentally detected as an Arrhenius, exp(E/T), temperature-dep

Phases of gallium nucleated by small particles
Autor: Daniel Teske, John E. Drumheller
Publikováno v: Journal of Physics: Condensed Matter. 11:4935-4940
Several structural phases of gallium can be nucleated upon cooling of mixtures of liquid gallium and an excess of particulate material. One such structural phase, which we label the theta phase, was observed in gallium and fullerene mixtures and is e

Modulated microwave absorption spectra from Josephson junctions on a scratched niobium wire
Autor: Kala Subbaraman, K. Ravindran, Stuart L. Hutton, R. S. Rubins, John E. Drumheller
Publikováno v: Physical Review B. 55:12662-12665
Modulated microwave absorption (MMA) spectra from Josephson junction formations on a scratched Nb wire have been studied at 9.3 GHz and 4 K. The peak-to-peak separation, {delta}H of the Josephson lines was found to vary linearly with P{sup 1/2}, wher

ELECTRON PARAMAGNETIC RESONANCE DETECTION OF SOLITONS IN TWO-DIMENSIONAL MAGNETS
Autor: John E. Drumheller, C. E. Zaspel
Publikováno v: International Journal of Modern Physics B. 10:3649-3671
It has previously been assumed that spin waves were the dominant excitations in lower-dimensional magnets. Recently, however, it has been shown that nonlinear excitations or solitons rather than spin waves influence the dynamic thermal quantities suc

Crystal Structure and Magnetic Susceptibility Study of Pyrrolidinium Trichlorocuprate(II)
Autor: Mingyi Wei, Kala Subbaraman, Daniel Teske, Roger D. Willett, John E. Drumheller
Publikováno v: Inorganic Chemistry. 35:5781-5785
The title compound, (C4NH10)CuCl3, is shown to exist in two phases, the previously reported α phase and a new β phase. DSC studies indicate that the β phase transforms to the α phase at 93 °C. The β phase is stable at the room temperature, with
