This paper reports the discovery that a simply measured magnetic response is singular above the Curie temperature of a model, disordered magnet, and that the associated singularity grows to an anomalous divergence at TC. The origin of the singular response is the random internal field induced by an external magnetic field transverse to the favoured direction for magnetization.
