WebOct 1, 1990 · Apparently, only Dy impurity develops the appropriate SO 4--V Ca centres needed for observation of these peaks. The peak-3-related centres are shown to be quite different in behaviour from that of the structurally similar peak-1 - related SO 4--V Ca centres. These results emphasise the importance of Dy impurities in stabilising the TL … WebIn the Security Console, click Identity > Users > Manage Existing.

Ferromagnetic resonance measurements show that an increase of Dy doping from 0.1% to 5% gives a tripling in Gilbert damping, and more importantly a strongly enhanced anisotropic damping that can …
WebThe Dy4+/Dy3+ ratio can, in principle, be increased by preparing the material under highly oxidizing and Ba-rich conditions and co-doping with acceptor-like impurities; however, post- synthesis treatment may still be needed to realize a non-negligible Dy 4+ concentration. WebDy) impurity peaks marked by a black square ( ), a black star (★), or a black diamond (♦) respectively.

Websingle crystals with Dy atoms changes the p-type conductivity to the n-type, suggesting that the Dy impurity acts as a donor in Bi 2 Te 3. From the Hall data, it follows that the doping of Bi 2 Te 3 single crystals with the Dy impurity provides an electron concentration of 3 × 1018 cm–3. In this case, upon doping bismuth telluride, dysprosium WebDy 353.170 -0.03170 Eu 272.778 +0.02131 Sm 388.528 -0.03333 Tb 367.635 +0.03637 Yb 289.138 -0.03357 * (-) distance to the left of the peak and (+) distance to the right of the peak Table 1: Experimental system and operating parameters Equipment brand JY HORIBA ULTIMA 2 Frequency 40 MHz Operating power 1.0 kW Plasma gas flow 16 l/min
