By using chemical transport reactions with various transporting agents (HgCl2, NbCl5, Nb3O7Cl) a slightly substoiehiometric NbO2-phase, β-NbO2, was obtained from samples with O/Nb ∼ 1.5 (source; T > 1373 K) and with deposition temperatures > 1273 K (sink). The rango of composition of β-NbO2 was found to exist from NbO1.990 to NbO1.998.The structure of the tetragonal, column-shaped black crystals was determined by X-ray diffraction. It crystallizes tetragonally in the space group I41 with lattice constants a = 9.693(3) Å, c = 5.985(1) Å and Z = 10 formula units.The crystal structure of β-NbO2 is shown to be a deformed rutile type. As in α-NbO2 the Nb-atoms are grouped in pairs. However, both oxides are different with respect to their long-range order.

AbstractThe x-ray diffraction (XRD) of InGaAs/InP short-period superlattices (SPSL's) grown on (001)InP substrates by gas source molecular beam epitaxy (GSMBE) and by gas source migration enhanced epitaxy (GSMEE) shows that the GSMBE grown SPSL is strain free, and that GSMEE grown SPSL's with InGa-P and In-As heterointerfaces have strain-induced zerothorder satellite peak shift consistent with that in simulation results for the InGaAs/InP SPSL with one monolayer of InGaP and InAs inserted in each interface. Partial destruction of the long-range order is confirmed by the observation of the extra diffraction peak in GSMBE grown SPSL and by weak intensity of satellite peaks and nonuniform spacing between satellite peaks in GSMEE grown SPSL's. Raman scattering shows that the strain is accommodated in the interface layer in GSMEE grown samples. A confinement model without interface disorder fits the GaAs LO phonon very well. These results indicate that the local atomic arrangements are tailored by GSMEE, but that long range-order is impaired by the misfit dislocations in GSMEE grown SPSL's and by the exchange between As to P at the interfaces in GSMBE grown SPSL.

ABSTRACTChanges in the degree of long-range order of 10 μm thick FePd foil are presented and compared with results on 50 nm thick FePd films. The films were produced by dc and rf magnetron co-sputtering on Si as well as by molecular beam epitaxy co-deposition on MgO substrates. Long-range order was studied by electrical resistivity measurement, X-ray diffraction and Möβbauer spectroscopy.

Telah dilakukan analisis perbandingan parameter long-range order dalam satu sudut pandang pada logam paduan Al-5052 yang diberikan perlakuan ECAP dan annealing pasca ECAP. Sudut pandang yang dipakai adalah sudut pandang tegak lurus bidang (220). Dalam analisis, bidang fundamental adalah bidang (111), sementara bidang superlattice diasumsikan bidang (220). Terdapat 4 sampel uji Al-5052 yang digunakan. Keempat sampel diberikan perlakuan ECAP rute Bc sebanyak 4 pass. Kemudian, 3 dari 4 sampel diberikan perlakuan annealing pasca ECAP dengan variasi temperatur annealing 100 oC, 200 oC, dan 300 oC, sementara satu sampel tersisa sebagai kontrol pembanding. Karakterisasi dilakukan dengan analisis x-ray diffraction. Hasil analisis menunjukkan nilai parameter order sampel tanpa annealing, sampel dengan temperatur annealing 100 oC, sampel dengan temperatur annealing 200 oC, dan sampel dengan temperatur annealing 300 oC secara berturut-turut adalah 0.54526, 0.693152, 0.92553, dan 1.183165. Dengan demikian, terjadi perubahan kondisi dari kondisi lebih disordered menjadi lebih ordered akibat perlakuan annealing pasca ECAP. Sementara itu, kondisi fully ordered diprediksi terjadi saat penerapan temperatur annealing 226.065704 oC. Dari studi ini dapat disimpulkan bahwa metode perbandingan parameter order ini dapat digunakan sebagai acuan kontrol kualitas logam paduan Al-5052 setelah proses annealing pasca ECAP. Namun, analisis ini tidak direkomendasikan untuk menentukan nilai mutlak parameter order, namun hanya direkomendasikan untuk dibandingkan antar sampel satu sama lain.
