MAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON
The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...

متن کاملElectron spin dynamics and electron spin resonance in graphene
A theory of spin relaxation in graphene including intrinsic, Bychkov-Rashba, and ripple spinorbit coupling is presented. We find from spin relaxation data by Tombros et al. (Nature, 448 (2007) 571) that intrinsic spin-orbit coupling dominates over other contributions with a coupling constant of 3.7 meV. Although it is 1–3 orders of magnitude larger than those obtained from first principles, we ...
متن کاملThermal lability of membrane proteins of age separated erythrocytes as studied by electron spin resonance spin label technique.
Thermal lability of bovine erythrocyte membrane proteins was studied by electron spin resonance using maleimide spin label. The temperature of the sample during measurements could be varied for the first time between 0 and 60 degrees C with an accuracy of +/- 0.1 degrees C. Our results show that "old" erythrocyte membrane proteins are less stable against thermal denaturation then "young" cells.
متن کاملImmobilization-induced changes in erythrocyte membrane fluidity in rabbits: a spin-label electron spin resonance study.
It has been shown that many diseases are linked to abnormalities of the erythrocyte membrane. This study observed the changes in erythrocyte membrane fluidity during an immobilization period of 21 days. The right hindlimbs of male adult New Zealand white rabbits were immobilized for 21 days. Blood samples were collected and heparinized prior to immobilization and on days 1, 3, 7, 14, and 21 of ...
