Experimental evidence has been found that magnetic poles within metal oxide magnets can be separated. A bar magnet has a north and south pole, and cutting it in half just creates two new poles, not two separated monopoles. However, a recent theoretical proposal suggested that defects in the spin alignment of certain oxide magnets can create separated effective magnetic monopoles (1). These materials are called spin ices because the lowest-energy orientation of the magnetic spins closely mimics… CONTINUE READING
