本文主要研究内容
作者（2019）在《Magnetocaloric and magneto-transport properties of Gd10Co20Si70alloy》一文中研究指出：We report the results of magnetic, thermodynamic, transport and magnetocaloric effect （MCE） studies of newly synthesized Gd10Co20Si70 alloy. These measurements confirm an antiferromagnetic transition at TN=9 K. Both MCE and magnetoresistance （MR） show quadratic dependence on the applied magnetic field, indicating the presence of spin fluctuations in the alloy. The maximum values of the magnetic entropy change determined from the isothermal magnetization data for magnetic field change of 7 and9 T are found to be 10.5 and 15.6 J/kg·K, respectively. As a consequence of the spin fluctuations effect, the MCE peaks are pulled towards high temperature side as asymmetrically broadened peak. The MR attains a large positive value of 73%at 2 K in 8 T. The large MR and reversible MCE make this alloy an attractive multifunctional magnetic material.
Abstract
We report the results of magnetic, thermodynamic, transport and magnetocaloric effect （MCE） studies of newly synthesized Gd10Co20Si70 alloy. These measurements confirm an antiferromagnetic transition at TN=9 K. Both MCE and magnetoresistance （MR） show quadratic dependence on the applied magnetic field, indicating the presence of spin fluctuations in the alloy. The maximum values of the magnetic entropy change determined from the isothermal magnetization data for magnetic field change of 7 and9 T are found to be 10.5 and 15.6 J/kg·K, respectively. As a consequence of the spin fluctuations effect, the MCE peaks are pulled towards high temperature side as asymmetrically broadened peak. The MR attains a large positive value of 73%at 2 K in 8 T. The large MR and reversible MCE make this alloy an attractive multifunctional magnetic material.
