Intercalation compound FePS3 (CoCp2 )0.40 (CoCp2 = cobaltocene) was synthesized, and the crystal structure and magnetic properties were studied by x-ray diffraction, magnetic susceptibility measurement, and Mossbauer spectroscopy. The crystal structure was indexed to monoclinic unit cell with a = 5.996A, b = 10.106A, c =12.511 A, β = 105.916°, and about 5.6 A expansion at the c-direction compared to pure FePS3. The Mossbauer spectra indicate that there are three kinds of divalent ions with high spin state in the intercalation compound,which implies charge transfer from guest to the Fe-S e*g anti-bonding orbits of the host lattice. No cationic vacancies are formed in the intercalation compound. The ferromagnetism at low temperature originates from the spin canting of divalent ions.

现在的高考命题由“知识立意”向“能力立意”转变，这就要求学生能灵活运用所学知识解题。因此，在课堂教学中培养学生的主动学习能力相当重要。笔者认为可以从以下几方面进行： 一、使学生明确教学目标 教师可用投影仪亮出每节课的教学目标，让学生明确教材中的知识内容，哪些需要识记，哪些需要理解，哪些还需要进一步应用。这样学生便有目的地进行探索，而不至于盲目、 被动地接受知识。有时教师还可以结合教学目
初中年龄段的学生，活泼好动、精力充沛，勇于探索，好奇心盛，求知欲强，具有较强的创新潜能。初中物理实验教学既能为学生正确认识事物及发现事物间存在的客观规律提供事实依据，又能培养学生观察现象、分析问题、解决问题的能力，同时实验教学还以其生动的魅力和丰富的内涵为学生发挥创造潜能提供独特的创造环境。 几年的初中物理教学，让我深切感到用实验导入，以实验求知，总结后进行实验操作，这样的教学模式对初步养成学生
