A student experiment is described concerning properties of ferromagnets near the Curie point. Gadolinium provides a good opportunity to determine the magnetic susceptibility above the transition point and to evaluate the critical exponent of the susceptibility. The temperature dependence of the electrical resistance of nickel at enhanced frequencies shows the influence of the magnetic properties of the sample on the skin depth. From the measurements, the phase transition is clearly seen and the temperature dependence of the magnetic permeability below the Curie point is available. Data on the resistance at an enhanced frequency reveal the phase transition in a nickel-based alloy. These items may be added to related student experiments described previously.
