Insight-HXMT was designed to have a broad energy coverage in X-rays, from 1-250 keV, with excellent timing and adequate energy resolution at soft X-rays, and the largest effective area at hard X-rays. This allows, in particular, to observe bright sources like X-ray binaries (XRBs) in their bright/outburst states with high cadence and high statistics at hard and soft X-rays at once. It was then expected that the Insight-HXMT mission will bring us new insights regarding the characteristics of several source classes. Examples include characterizing High-Mass X-ray Binaries (HMXBs) and the outburst evolution of Low-Mass X-ray Binaries (LMXBs). For instance, in HMXB systems, the region around their Alfven radius that is responsible to determine whether accretion or propeller occurs, or the region around the NS magnetic pole where the intense X-rays are supposed to be produced are specially appealing targets of study. For the LMXBs, the evolution the outburst and the properties of the compact objects themselves are obvious priority targets for Insight-HXMT. Due to the broad coverage in energy, Insight-HXMT is specially well suited to study the influence of thermonuclear (type-I) X-ray bursts upon the surrounding environment.   A New Set of Parameters of High-Mass X-ray Binaries Found with their Cyclotron Lines 期刊论文  OAI收割 arXiv e-prints, 2018 作者:  Zhang, Chengmin;  Taani, Ali;  Chaty, Sylvain;  Karino, Shigeyuki;  Song, Liming   |  收藏  |  浏览/下载：75/0  |  提交时间：2019/07/12 Astrophysics - High Energy Astrophysical Phenomena  Abstract: We have derived new physical quantities for several High-Mass X-ray Binaries (HMXBs) with supergiant (SG) companions through their cyclotron lines. The parameters are: the terminal velocity of the wind, the mass loss rate of the donor, the effective temperature and the magnetic fields. These parameters influence significantly the improvement of the model of accretion. In spite of the variety of their observational properties, the corresponding magnetic field is around B ~ 10^12 G. This result can be constrained by the effects on stellar evolution. In addition, we have performed a segmentation in the parameter space of donors intended for several SG-HMXB listed in our sample set. The parameter space can be categorized into five regimes depending on the possibility of disk formation associated with accretion from the stellar wind. This can give a quantitative clarification of the observed variability and the properties of these objects. We show that, when these systems come into the direct accretion region, systems with corresponding parameters can emit X-rays.   Magnetocaloric effect and spontaneous magnetization in perovskite manganite Nd0.55Sr0.45MnO3 期刊论文  OAI收割 MATERIALS RESEARCH BULLETIN, 2016, 卷号: 73, 期号: 无, 页码: 187-191 作者:  Xu, Lisha;  Fan, Jiyu;  Zhu, Yan;  Shi, Yangguang;  Zhang, Lei 收藏  |  浏览/下载：54/0  |  提交时间：2017/12/07 Ceramics  Magnetic Materials  Magnetic Properties  Phase Transitions  Equations-of-state   Anomalous Hall effect in perpendicular CoFeB thin films 期刊论文  OAI收割 CHINESE PHYSICS B, 2014, 卷号: 23, 期号: 4 Zhu, T 收藏  |  浏览/下载：36/0  |  提交时间：2015/04/14 anomalous Hall effect  perpendicular magnetic anisotropy  magnetic properties of interfaces   Structure and magnetic properties of (Al, Co) Co-doped ZnO thin films (EI CONFERENCE) 会议论文  OAI收割 2012 International Conference on Materials Science and Nanotechnology, ICMSN 2012, November 16, 2012 - November 18, 2012, Guangzhou, China Cao P.; Bai Y. 收藏  |  浏览/下载：30/0  |  提交时间：2013/03/25 In this study  Zn0.99Co0.01Al0.015O thin film has been prepared by sol-gel method. The structural and magnetic properties of the sample were investigated. X-ray diffraction spectroscopy analyses indicate that the Co and Al codoping can not disturb the structure of ZnO. No additional peaks are observed in the Zn0.99Co0.01Al xO and Al3+ and Co2+ substitute for Zn 2+ without changing the wurtzite structure. The resistance measurements confirm that Al ions increase the free carriers concentration. Based on the above experiments we think the ferromagnetic behavior of the sample could not originate from Co nanoclusters. The presence of free carriers and localized d spins is a prerequisite for the appearance of ferromagnetism. As the result  the carriers generated by Al doping is considered a main factor to induce the ferromagnetic phenomenon.
