<p class="MsoNormal"><span style="font-size:11.5pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:14.0pt">5d transition-metal oxides such as iridates have recently attracted growing interest because of their potential for realizing new topological phases (e.g. the Weyl semimetal phase) that arise from the interplay
of strong spin-orbit interaction and electron correlation. In order to realize these topological states, it is essential to study the magnetic properties as the electronic structures are strongly coupled with the magnetic ground states. In this talk, I will
present our recent studies of magnetic properties of some important iridates, including the pyrochlore iridates and the double- perovskite compounds. In particular, I will present our magnetic susceptibility measurements and electron spin resonance study that
suggest the existence of novel magnetic ground states in these complex compounds. I will also discuss the potential origins of magnetic ordering at low temperatures.</span><span style="font-size:14.0pt;font-family:"Times New Roman",serif"><o:p></o:p></span></p>
