Abstract
- The effects of iron, copper, and niobium alloying additions on crystallization, phase transformation, and magnetic properties of Mn–Si–B-based amorphous ribbons were studied by X-ray diffraction (XRD), differential scanning calorimeter (DSC), and physical property measurement system (PPMS). The DSC results show that Mn<subscript>78</subscript>Si<subscript>13</subscript>B<subscript>9</subscript> amorphous sample presents one-stage crystallization reaction. When added the alloying elements of iron, copper, and niobium into Mn–Si–B alloy system, the alloys still exhibit one-stage crystallization behaviors, but the crystallization temperature (T<subscript>x</subscript>) has changed. The alloying addition of iron in Mn–Si–B alloy makes a decrease in T<subscript>x</subscript>, while making further microalloying additions of copper and niobium in Mn–Fe–Si–B alloy the T<subscript>x</subscript> of the alloy elevates significantly. For Mn<subscript>78</subscript>Si<subscript>13</subscript>B<subscript>9</subscript>, Mn<subscript>68</subscript>Fe<subscript>10</subscript>Si<subscript>13</subscript>B<subscript>9</subscript>, and Mn<subscript>64</subscript>Fe<subscript>10</subscript>Si<subscript>13</subscript>B<subscript>9</subscript>Cu<subscript>1</subscript>Nb<subscript>3</subscript> alloys, the crystallization of amorphous phase simultaneously forms α-Mn(Si), Mn<subscript>6</subscript>Si, and Mn<subscript>2</subscript>B phases upon heating above the glass transition temperature. Besides, the thermal-magnetization M(T) curves confirm that the amorphous Mn<subscript>78</subscript>Si<subscript>13</subscript>B<subscript>9</subscript> and Mn<subscript>68</subscript>Fe<subscript>10</subscript>Si<subscript>13</subscript>B<subscript>9</subscript> samples exhibit a characteristic spin-glass behavior. The spin-glass freezing temperatures of them are about 20 ~ 22 K. [ABSTRACT FROM AUTHOR]
