The Critical Pair‐Breaking Current in Superconductors
Physica Status Solidi (B): Basic Research - Tập 191 Số 1 - Trang 189-192 - 1995
N. Rezlescu, Cristina Buzea, Maricel Agop
AbstractA new way of estimating the critical pair‐breaking current is developed. The superconducting charge carriers are considered as quantized vortex‐like objects, characterized by Γ — the vortex strength, Γ = h/2m. Taking into account that the charge carriers are confined in the CuO planes, and applying the von Karman theory for vortex...... hiện toàn bộ
Color Centers in Quartz Produced by Crushing
Physica Status Solidi (B): Basic Research - Tập 3 Số 12 - Trang 2275-2279 - 1963
J. Arends, Arnold J. den Dekker, W. G. Perdok
AbstractResults are presented for electron spin resonance measurements carried out at room temperature on freshly powdered high purity quartz and fused silica. As a result of the powdering, unpaired electrons are produced in concentrations of 1014 to 1015 per gram, depending on the particle size. The thermal stability of th...... hiện toàn bộ
Temperature Shift, Recoil‐Free Fraction, and Force Constant in Mössbauer Studies
Physica Status Solidi (B): Basic Research - Tập 51 Số 1 - Trang 233-239 - 1972
Govind P. Gupta, K. C. Lal
AbstractA simple relation connecting the temperature shift, the recoil‐free fraction, and the force constant has been derived. The force constants for host–host and for impurity–host atoms and their ratios have been calculated from this relation. The values thus obtained are compared with the values obtained by other authors. The agreement has been found to be sati...... hiện toàn bộ
Der Restwiderstand von Aluminiumlegierungen bei der Entmischung
Physica Status Solidi (B): Basic Research - Tập 3 Số 9 - Trang 1661-1671 - 1963
R. Labusch
AbstractDer elektrische Widerstand Q von kugelförmigen silber‐ und zinkreichen Zonen in AlAg‐und AlZn‐Legierungen wird mit Methoden der Transporttheorie behandelt. Die experimentell gefundene Abhängigkeit des Widerstandes vom Zonenradius R mit einem Maximum bei etwa 10 Å weist auf ein Leitungsband hin, bei dem...... hiện toàn bộ
Antiferromagnetism in an oxide semiconducting glass
Physica Status Solidi (B): Basic Research - Tập 45 Số 1 - Trang 323-331 - 1971
E. J. Friebele, L. K. Wilson, Ashley Dozier, D. L. Kinser
AbstractThe magnetic structure of a 55 mol% FeO–45 mol% P2O5 semiconducting glass containing various relative concentrations of Fe3+ and Fe2+ has been studied by ESR techniques over the temperature range −190 to 300 °C. It was determined that the iron ions in the glass matrix are an...... hiện toàn bộ
Susceptibility of an amorphous antiferromagnet
Physica Status Solidi (B): Basic Research - Tập 42 Số 1 - 1970
S. Kobe, K. Handrich
An Effective Field Model of the Amorphous Antiferromagnet
Physica Status Solidi (B): Basic Research - Tập 40 Số 1 - Trang 207-220 - 1970
A. W. Simpson
AbstractAn effective field model of an amorphous antiferromagnet is developed assuming a distribution of near neighbour distances and hence a distribution of effective field coefficients between interacting atom pairs. It is shown that such a material is characterized by a symmetrical distribution of the total effective field, which, in the absence of any spin corr...... hiện toàn bộ
A simple model for amorphous antiferromagnets
Physica Status Solidi (B): Basic Research - Tập 44 Số 2 - Trang 613-617 - 1971
R. Hasegawa
AbstractA molecular field model for amorphous antiferromagnets is considered by taking into account the structural fluctuations which could exist in amorphous materials. The results show that the fluctuations shift the susceptibility versus temperature curves towards or away from the temperature axis with changes in the Néel temperatures. The direction of the shift...... hiện toàn bộ
ESR Studies of Cupric Ion in Various Oxide Glasses
Physica Status Solidi (B): Basic Research - Tập 30 Số 2 - Trang 469-478 - 1968
Hiroshi Imagawa
AbstractESR spectra of cupric ions in borate, silicate, and phosphate glasses were analyzed by the LCAO MO method of Maki and McGarvey. The covalency of the B2g π‐orbital was found to change with the bond strength of the network‐former. Particularly it reflected clearly the weakening of BO bonds in alkali borate glas...... hiện toàn bộ
