摘要：

This paper presents an experimental study of the magnetic anisotropy of blood cells in magnetic field up to 1.8 T and in temperature range of 75 - 295 K by means of torque method. Magnetic field can induce a marked uniaxial anisotropy. The effective anisotropy constant K-1eff does not depend on temperature. Magnetic-induced anisotropy of investigated samples cannot be explained by diamagnetic shape anisotropy of individual blood cells. A tendency to aggregate into chains and small groups of hemoglobin particles and conversion into methemoglobin with high spin Fe3+-ion is considered. (C) 1999 Elsevier Science B.V.
