Assuming that graphite particles are responsible for the observed polarization in late‐type variables the sizes of the grains are derived to about 10 −6 cm. Further it is shown that the lower limit for the strength of the magnetic field in the atmospheres of these stars lies between 0·3 and 10 Gauß.
