- Аннотация: Magnetic properties of DNA liquid-crystal dispersions are experimentally investigated by SQUID magnetometer. The magnetic susceptibility of pure DNA and DNA doped by La, and Gd is measured in the region 4.2–300 K. The total magnetic moment is represented as a sum of the paramagnetic part and negative diamagnetic part. The number of paramagnetic Gd3+ ions is calculated in a good agreement with the number of phosphate complexes. The temperature dependence of magnetic susceptibility indicates the presence of interaction between Gd3+ magnetic moments, which is discussed in terms of long-range RKKY-type exchange in one-dimensional metals. Magnetic properties of DNA dispersions are investigated by SQUID magnetometer. • The magnetic susceptibility of pure DNA and DNA doped by La and Gd is measured. • The presence of long-range interaction between Gd3+ magnetic moments. • The model of RKKY-type exchange in one-dimensional metals is discussed.
