⁵⁷Co has been oriented in an iron foil at temperatures down to 12.7 moK. The ⁵⁷Co magnetic moment was measured by taking temperature-dependent ⁵⁷Co and ⁶⁰Co data, and the result was μ(⁵⁷Co) = 4.733±0.023 n.m. The mixing ratios, δ = E2/M1, of the intense 122 keV γ-ray as well as of the weak ⁵⁷Fe γ-rays, resulting from the decay of the 707 keV level, were measured. We obtained δ (122) = 0.1195±0.0010, −0.186 < δ (230) < 0.072 or −6.99 < δ (230) <− 2.38, δ (352) = 0.038±0.010 or 3.35±0.12, δ (367) = −0.047±0.025 or −1.56±0.09, δ (340) = 0.0827±0.0051, δ (570) = 0.0974±0.0081 and δ (692) = −0.4654±0.0082.
