Study of a successive component-separated magnetic transiton and a partial magnetic ordered phase

四方相稀土三元化合物HoRh 2Si 2显示出所谓的“连续组分分离的磁性转变”，即磁矩的c-和ab-组分在不同温度下发生独立的排序。为了阐明这种转变的起源，测量磁化强度，磁化率，比热，弹性常数和中子衍射进行了单晶化合物具有良好的质量。结果表明，该化合物存在阻挫现象，四极相互作用对该跃迁起重要作用。

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.
