| Research Abstract |
The teragonal rear earth ternary compound HoRh2Si2 shows so-called "a successive component-separated magnetic transition"; that is, independent orderings of the c- and ab-component of magnetic moments occur at different temperatures. In order to elucidate the origin of this transition, measurements of magnetization, magnetic susceptibility, specific heat, elastic constants and neutron diffraction were performed on single crystal compounds with good quality. From the results, it was found that a frustration occurs in this compound and quadrupolar interactions play an important role for the transition.
