The low temperature phase (LTP) of MnBi, an interesting material with large magnetic anisotropy, has been obtained for the first time in bulk quantities in almost single-phase form ($>$95$ sp{wt}$%) by melt-spinning, followed by annealing. / X-ray, electron microscope and differential scanning calorimetry (DSC) studies indicate that the melt-spun MnBi is amorphous, and may be phase separated. A mechanism is suggested for the glass formation in MnBi. Upon heating, amorphous MnBi first crystallizes around 440 K, then forms LTP around 540 K. DSC and thermomagnetometry studies show that the LTP transforms to high temperature phase around 630 K through two separate processes: a composition transition and a magneto-structural transition. / The anisotropy field, $H sb{a}$ of LTP, is measured from 147 to 586 K by a pulsed magnet combined with the singular point detection technique (SPD). $H sb{a}$ increases with temperature, and reaches a maximum value of 9 T at 530 K. The critical field for spin reversal of a ferrimagnetic phase of MnBi is also detected by SPD from 80 to 200 K, reaching a maximum value of 8 T at 120 K. The coercivity of LTP is successfully described by a model of domain wall pinning which predicts, at 300 K, a domain wall energy of 15.7 $erg/cm sp2$ and a wall thickness of 70 A.

Current practices for routine milk composition determination employ commercial infrared systems. The use of SW-NIR and NIR FT-Raman spectra coupled with conductivity and refractive index could lead to more frequent and less costly analysis of fat, lactose and protein in milk. / The present study examines the potential of both SW-NIR absorbance spectrophotometry and NIR FT-Raman spectrophotometry to develop a model to estimate fat, lactose, and protein in whole milk of cows. To accomplish this, 79 milk standards, spanning the range of composition seen in practice, were obtained. Acquisition of NIR spectra over the wavelength range of 700 nm to 1018 nm was conducted. Between 0 and 3700 cm-1, NIR FT-Raman spectrophotometric measurements of the milk samples were made using a 1064 nm Nd: YAG laser source. Conductivity and refractive index measurements were also obtained for the milk standards. / A partial least squares calibration with leave-N-out cross validation was made using spectra with conductivity and refractive index to estimate fat, lactose and protein contents. Calibrations were developed using 75% of the milk standards. Models were further validated using an independent test set comprised of the remaining 25% of the data that had been excluded from calibration. A second calibration was conducted using a genetic algorithm approach. (Abstract shortened by UMI.)
