Abstract
We contend that the anomalies observed in the magnetization, specific heat, and thermal expansion of CaMn7O12 at T S = 89 K and T M = 49 K reported in O. Volkova et al., Pis’ma v ZhETF 82, 498 (2005) [JETP Lett. 82, 444 (2005)] and mentioned in Pis’ma v ZhETF 82, 724 (2005) [JETP Lett. 82, 642 (2005)] are both of magnetic origin.
