Beschreibung: Author(s): K. Kimura, M. Toyoda, P. Babkevich, K. Yamauchi, M. Sera, V. Nassif, H. M. Rønnow, and T. Kimura A material with broken space-inversion and time-reversal symmetries can exhibit symmetry-dependent unique phenomena such as the magnetoelectric effect. Ferroic order of magnetic quadrupoles fulfills this symmetry condition. The authors report here the discovery of ferroic magnetic quadrupole order and its magnetoelectric activity in the novel compound Pb(TiO)Cu 4 (PO 4 ) 4 , which is in contrast with isostructural Ba(TiO)Cu 4 (PO 4 ) 4 and Sr(TiO)Cu 4 (PO 4 ) 4 in exhibiting antiferroic quadrupole order. Their first-principles calculations reveal that s 2 electrons in Pb 2 + ions alter specific magnetic interactions and consequently switch the quadrupole order from antiferroic to ferroic. This result provides not only an opportunity to explore magnetoelectric phenomena arising from magnetic quadrupoles, but also a useful way of fine-tuning magnetic interactions with s 2 electrons.

Notizen: Abstract A four input-port and an eight output-port optoelectronic matrix switch using InGaAsP/InP hetero-junction switching photodiodes was fabricated and its characteristics studied. The characteristics of the broadband switching equipment, as well as those of individual components, such as the switching photodiodes, InGaAsP/InP semiconductor lasers, eight-port optical dividers and receiver circuits, are discussed from the viewpoint of analogue signal switching. The signal-to-noise ratio attained is more than 40dB for a 30MHz bandwidth television signal. Differential gain and differential phase are less than 2% and 2°, respectively, isolation is higher than 80 dB. Crosstalk between adjacent channels is suppressed below-60 dB over the band between d.c. and 100 MHz by a simple metallic shield at the input and output electric circuits.
