    Anomalous local magnetic field distribution and strong pinning in CaFe1.94Co0.06As2 single crystals

    Full text link
    Magneto-optical imaging of a single crystal of CaFe1.94Co0.06As2, shows anomalous remnant magnetization within Meissner like regions of the superconductor. The unconventional shape of the local magnetization hysteresis loop suggests admixture of superconducting and magnetic fractions governing the response. Near the superconducting transition temperature, local magnetic field exceeds the applied field resulting in a diamagnetic to positive magnetization transformation. The observed anomalies in the local magnetic field distribution are accompanied with enhanced bulk pinning in the CaFe1.94Co0.06As2 single crystals. We propose our results suggest a coexistence of superconductivity and magnetic correlations.Comment: 6 pages, 4 figures. arXiv admin note: substantial text overlap with arXiv:1201.369

    Isolated left atrial aneurysms are rare entities in clinical practice. Usually the condition is diagnosed in the second to fourth decades of life. The presence of such lesions in the pediatric age group is scantily described. We present a 2 year boy who presented with complaints of excessive irritability, respiratory distress and swelling of the feet. On examination, child was tachypnoeic with irregularly irregular rhythm. Echo showed a huge aneurysmal LA appendage with severe left ventricle dysfunction. The child underwent surgical resection for same. Findings were confirmed intraoperatively but he continued to have low cardiac output state after the surgery, with frequent arrhythmias and expired on day 7 of surgery. The case is reviewed and compared with the available English literature.peer-reviewe

    Taxonomic studies on wildlife biodiversity has always been very fascinating along with the great purpose of providing valuable information on their present status concerning species number and future course of action required for their conservation. A study regarding survey of flora and fauna was carried out at Dhauladhar Nature's Park of Gopalpur in district Kangra of Himachal Pradesh during the month of April 2015. The present study has revealed the presence of 09 mammals, 02 reptilia, 05 pheasants and 04 other birds belonging to 12 families along with 44 plant species belonging to 28 families. Further it is suggested that provisions for Himalayan snakes and butterflies, the other two imperative Himalayan fauna be created as soon as possible so that nature's park can fulfill its true purpose of conservation of Himalayan wild animals in real sense
