ON THE SEPARATION OF MAGNETICALLY MARKED CELLS BY DIAMETER USING FILMS WITH A STRIP DOMAIN STRUCTURE

This paper examines the change in the motion mode of magnetically marked cells with decreasing
diameter. For diameters less than or equal to a certain value, min D , the cells oscillate for oscillations that do not exceed the domain structure period,  . For cells with diameters greater than min D , the cells can, at a sufficiently low frequency of the external (control) field, move over distances much greater than the domain structure period. The mechanism for the formation of this minimum diameter is investigated. A similarity relation is obtained linking  , min D and the film thickness, h .
