Low temperature property of Metaphosphatecopper(II/I) salt
An inorganically template metaphosphoric acid containing copper salt, nanomaterial, has been synthesized and characterized with different measurement techniques such as Differential Scanning Calorimeter (DSC) UV Vis NIR, HRTEM, VSM, PPMS and X RD. The thermal property of this salt has been studied at a low temperature up to 223 K from 298 K with DSC. The specific heat capacity of this complex has been measured in atmospheric O2 at a rate of 10 K min 1 from 298 K to 223 K and vice versa in two thermal cycles. The net specific heat capacity of this salt is found 88.28 J/gm.K and 86.56 J/gm.K in first and second thermal cycles, respectively. There is a discontinuity in the specific heat at 106 s while measuring the specific heat capacity of the above nanomaterial at constant temperature 283 K. This particle size of this nanomaterial is 10 nm. The paramagnetic Curie temperature (thP) and Curie constant (C) are 18.29 K and 1.35x10 3 respectively. This material founds insulator from PPMS and UV Vis NIR mea.
