Free magnetic moments usually manifest themselves in Curie laws, where weak external magnetic fields produce magnetizations that vary as the reciprocal of the temperature (1/T). For a variety of materials that do not display static magnetism, including doped semiconductors and certain rare-earth intermetallics, the 1/T law is replaced by a power law T-α with α < 1. Here we show that a much simpler material system—namely, the insulating magnetic salt LiHoxY1-xF4—can also display such a power law… Expand
