The intermetallic compound URu2Si2 has mystified condensed matter physicists for over 25 years. All the fuss is over the so-called “hidden order” phase, which is associated with a large change in the electronic entropy, but whose order parameter seems to defy all experimental probes. In addition to discussing some of our recent experimental results, I will illustrate how materials synthesis, bulk property measurements, and specialized spectroscopies like neutron scattering, play complementary roles in these studies.
