Pr₂Fe₁₄C系急冷薄帯の磁気特性

抄録

We investigated the magnetic properties of melt spun Pr₂Fe₁₄C and several pseudoternary compounds of the type Pr₂(Fe, M)₁₄C and (Pr, R)₂Fe₁₄C. A value of iH_c∼1.3 kOe was obtained in Pr₂Fe₁₃MnC alloy ribbons. Heavy rare earth substitution leads to an increase in room temperature intrinsic coercivity. A value of iH_c=3 kOe, 6 kOe was achieved for (Pr_0.6Gd_0.4)₂Fe₁₄C, (Pr_0.6Dy_0.4)Fe₁₄C alloy ribbons, respectively, and large intrinsic coercivity of 18 kOe was found in Pr_7.9Dy_5.2Fe_79.7C_7.2 composition.
