<p class="MsoNormal"><span style="font-size:12.0pt">ABSTRACT: Magnetic monopoles, free magnetic charges, are long sought after entities in science. Independently in 2005 Ryzhkin [1] and in 2008 Castelnovo, Moessner and Sondhi [2] predicted that defects in
a family of frustrated magnetic materials called "spin ice" could resemble magnetic charges. These predictions sparked interest in the experimental community and different experimental groups started to look for these defects. I will introduce spin ice, magnetic
monopoles and describe our search for evidence of these defects [3].<o:p></o:p></span></p>
