Enhancing the magnetoelectric coupling of Co4Nb2O9[100] by substituting Mg for Co

Frontiers of physics 2018年第5期13卷 73-78页

作者： Zhen Li Yi-Ming Cao Yin Wang Ya Yang Mao-Lin Xiang You-Shuang Yu Bao-Juan Kang Jin-cang zhang Shi-Xun Cao Department of Physics International Center for Quantum and Molecular Structures and Materials Genome Institute Shanghai University Shanghai 200444 China Center for Magnetic Materials Devices Key Laboratory for Advanced Functional and Low Dimensional Materials of Yunnan Higher Education Institute Qujing Normal University Qujing 655011 China School of Physics and Electronic Engineering Xinyang Normal University Xinyang 464000 China

We report experimental studies on enhancing the magnetoelectric （ME） coupling of Co4Nb2O9 by sub- stituting the non-magnetic metal Mg for Co. A series of single crystal Co4-xMgxNb2O9 （x = 0, 1, 2, 3） with a single-phase corundum-type structure are synthesized using the optical floating zone method, and the good quality and crystallographic orientations of the synthesized samples are confirmed by the Laue spots and sharp XRD peaks. Although the Neel temperatures （TN） of the Mg substituted crystals decrease slightly from 27 K for pure C04Nb2O9 to 19 K and 11 K for Co3MgNb2O9 and Co2Mg2Nb2O9, respectively, the ME coupling is doubly enhanced by Mg substitution when x = 1. The ME coefficient OlMg of Co3MgNb2O9 required for the magnetic field （electric field） control of electric polarization （magnetization） is measured to be 12.8 ps/m （13.7 ps/m）. These results indicate that the Mg substituted Co4-xMgxNb2O9 （x = 1） could serve as a potential candidate material for applications in future logic spintronics and logic devices.

Peach yield and fruit quality is maintained under mild deficit irrigation in semi-arid China

Journal of Integrative Agriculture 2017年第5期16卷 1173-1183页

作者： ZHOU Han-mi zhang Fu-cang Roger Kjelgren WU Li-feng GONG Dao-zhi ZHAO Na YIN Dong-xue XIANG You-zhen LI Zhi-jun College of Agricultural Engineering Henan University of Science and TechnologyLuoyeng 471003P.R.China Key Laboratory for Agricultural Soft and Water Engineering in Arid and Semiarid Areas of Ministry of Education Northwest A&F UniversityYangling 712100P.R.China Department of Plant Soils and Climate Utah State UniversityLogan 84322USA Institute of Environment and Sustainable Development in Agriculture Chinese Academy of Agricultural SciencesBeijing 100081P.R.China

We conducted a two-year study of deficit irrigation impact on peach yield and quality in semi-arid northwest China. Over two years, four-year-old peach trees were irrigated at 100, 75, 50 and 25% of peach evapotranspiration （ETc）, here, ETc= Coefficient （Kc）×Local reference evapotranspiration （ET0）. During the April-July fruit production season we measured root zone soil water depletion, sap flow velocity, net photosynthetic rate （Pn）, transpiration rate （Tr）, stomatal conductance （Gs）, water use efficiency （WUE=Pn/Tr）, fruit quality, and yield under a mobile rain-out shelter. Increased soil water depletion reasonably mirrored decreasing irrigation rates both years, causing progressively greater water stress. Progressive water stress lowered Gs, which in turn translated into lower T as measured by sap flow. However, mild deficit irrigation （75% ETc） constricted T more than Pn. Pn was not different between 100 and 75% ETc treatments in both years, and it decreased only 5-8% in June with higher temperature than that in May with cooler temperature. Concurrently under 75% ETc treatment, was reduced, and WUE was up to 13% higher than that under 100% ETc treatment. While total fruit yield was not different under the two treatments, because 75% ETc treatment had fewer but larger fruit than 100% ETc trees, suggesting mild water stress thinned fruit load. By contrast, sharply decreased T and Pn of the driest treatments （50 and 25% ETo） increased WUE, but less carbon uptake impacted total fruit yield, resulting 13 and 33% lower yield compared to that of 100% ETc treatment. Irrigation rates affected fruit quality, particularly between the 100 and 75% ETc trees. Fewer but larger fruit in the mildly water stressed trees （75% ETc） resulted in more soluble solids and vitamin C, firmer fruit, and improved sugar：acid ratio and fruit color compared to the 100% ETo treatment. Overall, trees deficit irrigated at 75% ETc maintained yield while improving fruit quality and using less wate
