Nuclear Magnetic Resonance in Ferromagnetic MnSb and Cr_xMn_1−xSb

抄録

Nuclear magnetic resonance signals are observed from nuclei in domains and in domain walls in ferromagnetic manganese antimonide. Internal magnetic fields are measured at the manganese, antimony sites at 77 K and 296 K. The difference in the internal magnetic fields measured at the Sb site using the Sb¹²³, Sb¹²¹ resonances respectively could be explained to a hyperfine anomaly ₁₂₁Δ₁₂₃=−(0.36±0.05)%. Resonance signals are also observed in Cr_xMn_1−xSb (x=0.01, 0.03 and 0.05). The observed broadening of the resonance lines is discussed.
