Nuclear magnetic resonance measurements were performed for high‐pressure synthesized alkaline‐metal–cobalt Laves phase compounds, cubic CaCo 2 and hexagonal MgCo 2 . 59 Co ferromagnetic nuclear resonances corresponding to hyperfine fields of –15.7 and –8.0 T were found for CaCo 2 and MgCo 2 , respectively, indicating relatively large spontaneous Co moments in these compounds in contrast to zero or induced Co moments in the rare‐earth–cobalt Laves phase system.
