论文摘要
我们进行了晶体生长，以使用激光二极管加热的浮动区（LDFZ）方法获得了手性控制的对映体晶体，并具有组成梯度进给杆。有人认为，$ t $ si（$ t $：过渡金属）的晶体均匀性是固定的，具体取决于$ t $在传统方法中生长的$ t $。我们发现COSI和MNSI的右手单晶分别是由由Fesi-Cosi和Fesi-MNSI组成的组成梯度进料棒生长的。获得的COSI和MNSI晶体从FESI的种子部分继承了手性，该部分在右手结构中生长，因此与文献中的晶体相反的手性。带有各种组合$ t $ SI化合物的饲料棒的LDFZ方法可以灵活控制$ t $ si的手性，对于阐明晶体性手性和手性诱发的物理反应之间的相互作用非常有用。
We performed a crystal growth to obtain chirality-controlled enantiopure crystals using a laser-diode-heated floating zone (LDFZ) method with a composition-gradient feed rod. It has been argued that the crystal handedness of $T$Si ($T$ : transition metal) is fixed depending on $T$ in the case of the ones grown by the conventional methods. We found that right-handed single crystals of CoSi and MnSi were grown from the composition gradient feed rods that consist of FeSi--CoSi and FeSi--MnSi, respectively. The obtained CoSi and MnSi crystals inherit the chirality from the seed part of FeSi, which grows in a right-handed structure, and thus have the chirality opposite to that for the crystals in the literature. The LDFZ method with the feed rods with various combinations of $T$Si compounds enables a flexible control of the chirality of $T$Si and will be useful for clarifying the interplay between the crystalline chirality and chirality-induced physical responses.
