| Research Abstract |
Generally the transition temperature of the multipole order is low, and measuring system down to very low temperature is indispensable. In this study, we succeeded in making a handmade NMR measuring system by using ^3He refrigerator which can be reaching down to 0.5 K. We performed the ^<11>B NMR measurement on (Tm^<0.5>Yb^<0.5>)B_6 in which a possibility of the multipole order was discussed. However, it was revealed that the origin of the phase transition is not a multipole but a magnetic dipole order. We also studied about CeRu_2Al_<10> showing an unique phase transition, and performed single crystal preparation, many macroscopic measurement, and ^<27>Al NMR.
