Hyperfine Structure in the Spectrum ofN14H3. I. …

Physical Review (1954)

G. R. Gunther-Mohr Robert L. White A. L. Schawlow William E. Good Donald K. Coles

The structure of the hyperfine spectrum of ${\mathrm{N}}^{14}$${\mathrm{H}}_{3}$ in the microwave region has been carefully re-examined. It has been found that the ${\mathrm{N}}^{14}$ quadrupole line spacings for $K\ensuremath{\ne}1$ can be fitted within experimental error to previously developed theory, provided a small change in the quadrupole coupling constant $\mathrm{eqQ}$ due to centrifugal distortion of the molecule is allowed for. For $K=1$; and $J=2, 3, 4$, a doubling of each line of the quadrupole pattern has been found which increases from about 70 to 150 kc/sec with increasing $J$. It has been possible to explain these new features of the spectrum in terms of the interactions of the magnetic moments of the protons with the molecular magnetic field caused by rotation and with the magnetic moment of the ${\mathrm{N}}^{14}$ nucleus.

Study of magnetic interactions in HoFeO3

Physical review. B, Solid state (1974)

J. C. Walling Robert L. White

The Ho-Fe and Ho-Ho interaction parameters are discussed in reference to optical Zeeman spectroscopic data and magnetization data on HoFe${\mathrm{O}}_{3}$. A molecular-field model is presented that incorporates these parameters in a systematic manner permitting accurate calculations of the ground-state pair Zeeman splitting constant and magnetization in the temperature region below about 60 \ifmmode^\circ\else\textdegree\fi{}K. By applying the model to existing data the authors are led to the tentative conclusion that Ho-Fe exchange is dominantly antisymmetric. In addition, the effect of an applied magnetic field upon the reorientation transition is explored in detail. The interesting result obtained is that previously unexplained anomalies in the magnetization data are found to be attributable to a spin orientation, and that both the usual reorientation transition and the field-driven transition are contained in the same molecular-field interaction theory.

Spectroscopic Identification and Direct Imaging of Interfacial Magnetic Spins

Physical Review Letters (2001)

Hendrik Ohldag Thomas J. Regan J. Stöhr A. Schöll F. Nolting

Using x-ray absorption spectromicroscopy we have imaged the uncompensated spins induced at the surface of antiferromagnetic (AFM) NiO(100) by deposition of ferromagnetic (FM) Co. These spins align parallel to the AFM spins in NiO(100) and align the FM spins in Co. The uncompensated interfacial spins arise from an ultrathin CoNiOx layer that is formed upon Co deposition through reduction of the NiO surface. The interfacial Ni spins are discussed in terms of the "uncompensated spins" at AFM/FM interfaces long held responsible for coercivity increases and exchange bias. We find a direct correlation between their number and the size of the coercivity.

Variable Temperature Infrared Spectroscopy Studies of Aromatic Acid Adsorbate Effects on Montmorillonite Dehydration

Applied Spectroscopy (2016)

Audrey L. Ingram Tara M. Nickels Dalia K. Maraoulaite Robert L. White

Molecular interactions between benzoic, salicylic, and acetylsalicylic acids and water contained within montmorillonite clay interlayer spaces are characterized by using variable temperature diffuse reflection infrared Fourier transform spectroscopy (VT-DRIFTS). By using sample perturbation and difference spectroscopy, infrared (IR) spectral variations resulting from the removal of interlayer water are used to characterize aromatic acid local environment changes. Difference spectra features representing functional group perturbations are correlated with changes in IR absorptions associated with –O–H and –C = O stretching vibrations. Results suggest that adsorbate carboxylic acid functionalities participate in extensive hydrogen bonding and that the strengths of these interactions are diminished when clays are dehydrated. The nature of these interactions and their temperature-dependent properties are found to depend on adsorbate structure and concentration as well as the clay interlayer cation.

Effects of catalyst acidity and HZSM‐5 channel volume on the catalytic cracking of poly(ethylene)

Journal of Applied Polymer Science (1995)

Rong Lin Robert L. White

Abstract The effects of catalyst acidity and the restricted reaction volume afforded by the HZSM‐5 zeolite structure on the volatile cracking products derived from poly(ethylene) are investigated. The effectiveness of silica‐alumina, HZSM‐5, and sulfated zirconia acid catalysts for poly(ethylene) cracking are compared. When high catalyst to polymer ratios are employed and volatile products are rapidly removed during cracking, the most abundant volatile products generated by poly(ethylene) cracking are propene and isoalkenes. The relative amount of propene produced and the temperatures corresponding to the maximum rate of volatile hydrocarbon production are found to be related to catalyst acidity. The restricted volume inside HZSM‐5 channels facilitates oligomerization and the production of small alkyl aromatics. © 1995 John Wiley & Sons, Inc.

Design and fabrication of bio-magnetic sensors and magnetic nanobead labels for DNA detection and identification

Digest of INTERMAG 2003. International Magnetics Conference (Cat. No.03CH37401) (2004)

S.X. Wang Robert L. White G.-X. Li V. Joshi Steven Sun

In this paper, the main challenges in developing a magnetic DNA microarray include: 1) The spin valve sensors must be sensitive to as few as 1-10 nanobeads to be useful for applications such as biological pathogen detection; to achieve this, the distance between the sensor and magnetic labels must be minimized. 2) The nanobeads must be monodisperse, water soluble, chemically and magnetically stable, and functionalized to attach to a DNA fragment; the nanobeads should also be superparamagnetic so that they will not agglomerate in the absence of applied fields. 3) The bio-magnetic DNA microarrays need to be designed to maximise the active sensing surface area.
