    • The present invention relates to a zero-valent transition metal complex which can be used as a starting material for producing a catalyst usable for producing a polyolefin by ring-opening metathesis polymerization of an olefin and an epothilone by ring-closing metathesis reaction, and a method for efficiently producing, at low cost, an organometallic compound useful as a catalyst, using the zero-valent transition metal complex as a starting material. Provided is a method for producing a zero-valent transition metal complex (C), which comprises reacting a divalent transition metal complex (A) with an olefin (B), the complex (A) being selected from the group consisting of a divalent ruthenium complex (A1) and a divalent osmium complex (A2), thereby obtaining a zero-valent transition metal complex (C), wherein the reaction is conducted under reducing conditions and after the reaction, the resultant crude product is extracted at high temperature using a saturated hydrocarbon as an extracting solvent. Also provided is a method for producing an organometallic compound, which comprises reacting the metal complex (C) with a specific compound (D) and a neutral ligand (E) in one step.

    • The magneto-optical recording medium is provided with a readout layer which shows the in-plane magnetization and which changes from the in-plane magnetization to the vertical magnetization when its temperature rises higher than a predetermined temperature by irradiation of the light beam, a memory layer which records information thereon magneto-optically, an intermediate layer which keeps in-plane magnetization from room temperatures to its Curie temperature, and an writing layer which has a Curie temperature higher than that of the memory layer and has coercive force lower than that of the memory layer. Since the intermediate layer becomes a domain wall in optical modulation recording, it prevents the memory layer and the writing layer from forming a domain wall, so information can be recorded in good condition. Moreover, a portion of the readout layer besides a center portion of the light beam shows the in-plane magnetization and masks the memory layer at playback. Therefore, a recording bit can be made small and recording density can be improved without increasing interference of signals from neighboring recording bits, which causes noises.
    • 磁光记录介质设置有读出层,该读出层显示平面内的磁化强度,并且当读出层的温度通过照射光束而升高到高于预定温度时,其从平面内磁化强度变化到垂直磁化强度;存储器 在磁光上记录信息的层,将室内的平面磁化保持到其居里温度的中间层,以及具有比存储层的居里温度高的居里温度并具有低于存储层的矫顽力的矫顽力的写层 内存层。 由于中间层成为光调制记录中的畴壁,因此防止存储层和写入层形成畴壁,因此可以将信息记录在良好状态。 此外,除了光束的中心部分之外,读出层的一部分表示平面内磁化,并且在重放时掩蔽存储层。 因此,可以使记录位小,并且可以提高记录密度,而不会增加来自相邻记录位的信号的干扰,这导致噪声。
