Selected Research Highlights

  • Band-Gap Moderated Slow Positive Muon Beams - Dr. Harshman led the research group that discovered the first practical technique for producing a low-energy (<10 eV) positive muon beam.  It was dubbed with the acronym, μSOL (muon separator online).  The same 1986 paper reported the first observation of (< 10 eV) Mu– (i.e., μ+e–e–) ions in vacuum.  In 1987, Dale Harshman and co-workers increased the slow muon production rate by a factor of 100 using solid rare-gas moderators, producing a usable flux of slow muons.  The slow muon production technique developed by Harshman and coworkers was adopted by the Paul Sherrer Institut for their slow positive muon beam facility.

  • Magnetic X-Ray Scattering in Holmium - This paper was the work cited for the 2003 Arthur H. Compton Prize given to its first and fourth authors.  In addition to taking part in all of the experiments, Dr. Harshman also designed, commissioned and supervised the building of the x-ray polarization spectrometer necessary for its success.

  • High-Temperature Superconductor Pairing State Symmetry - In 1987 using muon spin rotation (μ+SR) and measuring sintered powder samples of YBa2Cu3O7–δ, Harshman and coworkers provided the first measurements of the magnetic penetration and proof that the bulk pairing state of the superconducting hole condensate was nodeless, consistent with s-wave pairing and strong coupling.  Harshman and co-workers were also the first to measure the 60 K (oxygen-ordered) phase of YBa2Cu3O7–δ.  This research was followed by studies of heavily twinned single crystals of the same material, confirming the s-wave character and providing the first measurement of the mass anisotropy; mc ≥ 25 mab.  In 1991, Harshman and co-workers presented μ+SR data on single-crystal Bi2Sr2CaCu2O8+δ showing a strongly temperature-dependent line shape, indicative of motional narrowing arising from fluxon depinning.  The fluxon lattice in earlier powder and heavily-twinned crystal samples of YBa2Cu3O7–δ was strongly pinned, suppressing fluxon depinning.  However, by the mid 90's, the quality of YBa2Cu3O7–δ crystals improved greatly, revealing a text-book example temperature-activated fluxon depinning.  Unfortunately, some researchers misinterpreted the extrinsic effects of fluxon depinning as being evidence of d-wave pairing.  To correct this misrepresentation, Harshman and co-workers conducted series of μ+SR experiments on a single-crystal of  YBa2Cu3O7–δ, measuring the second moment of the frequency distribution, σ(T0,H), as a function of both temperature and applied field.  The strong (and non-monotonic) field dependence exhibited by σ(T→0,H), confirmed the presence of temperature-activated fluxon depinning.  By applying a self-consistent analysis approach, and accounting for the effects of fluxon depinning, Harshman and co-workers showed that the underlying gap function of the superconducting hole condensate was nodeless, and best described by the two-fluid model.  This line of research has proven that the bulk high-TC pairing symmetry of the hole condensate is nodeless, consistent with s-wave and strong coupling.

  • Oxygen Isotope Effect in High-TC Materials - For high-TC superconductors in which transition temperatures, TC, are reduced by doping, the oxygen isotope effect (OIE) coefficient in TC is shown to increase systematically with the pair-breaking rate and with the valence difference between the substituted and native ions.  Moreover, the OIE in Tc tends to zero as one approaches optimum (or ideal) stoichiometry at which the quality of the superconducting condensate is maximized.  In materials with isovalent substitutions, e.g., Sr for Ba or Zn for Cu in YBa2Cu3O7–δ, the small OIE of the parent (unsubstituted) compound is magnified, owing to pair-breaking disorder. In materials with heterovalent substitutions, e.g., La or Pr for Ba, where carrier densities are necessarily changed, pair-breaking induces a much larger OIE.  A seminal case is Pr-doped YBa2Cu3O7–δ, where data were previously misinterpreted, owing to the false assumption that Pr substitutes only for Y.  It is now clear, however, that the decrease in TC observed with Pr doping actually arises from pair-breaking caused by Pr-on-Ba-site defects introduced during crystal growth. When PrBa2Cu3O7–δ is grown correctly without such defects, TC remains unchanged (as in the case of most other rare earth substitutions for Y).  Invariance of TC under a 60% rare-earth mass increase provides strong evidence against phononic pairing mechanisms.  The fact that TC drops when Pr substitutes for Ba, but not for Y, indicates that the superconducting hole condensate resides in the BaO layers, where pair-breaking degrades TC and dramatically increases the OIE.  Superconductive pairing modeled on Coulomb coupling between the hole (BaO) and the electron (CuO2) layers is shown to resolve the serious shortcomings inherent in approaches based on electron-phonon interactions and is found to be generally applicable.  Moreover, the OIE in the magnetic penetration depth in alloys is shown to be constant, with degradation of TC up to 50%, and thus is unrelated to the OIE in TC.  This theoretical work corrects several earlier papers on the isotope effect in high-TC compounds, concludes non-phononic mediation and casts the isotope effect into isovalent and heterovalent substitutional categories.  Interpretations of differential OIE, combined with specific heat and and thermal conductivity data indicate two interacting mobile carrier bands: one of holes and the other, electrons.
