Abstract in another language
The magnetization curve of the commercially available ferrofluid EMG909 is measured. It can adequately be
described by a superposition of four Langevin terms. The effective dipole strength of the magnetic particles in
this fluid is subsequently obtained by a graphical rectification of the magnetization curve based on the inverse
Langevin function. The method yields the arithmetic and the harmonic mean of the magnetic moment distribution
function, and a guess for the geometric mean and the relative standard deviation. It has the advantage
that it does not require a prejudiced guess of the distribution function of the poly-disperse suspension of magnetic particles.
