An oscillating droplet method combined with electromagnetic levitation technique has been applied to determine the surface tensions of liquid pure iron, nickel and iron‐nickel alloys as a function of the temperature. The natural frequency of the oscillating droplet is evaluated using a Fourier analyser. The theoretical background of this method and the experimental set‐up were described, and the influence of magnetic field strength was also discussed. The experimental results were compared with those of other investigators and interpreted using theoretical models (Butler's equation, subregular and perfect solution model for the surface phase).
