The specific heat, magnetization, and magnetocapacitance of YbMnO 3 and YbMn 0.7 Ga 0.3 O 3 multiferroic single crystal manganites were measured in magnetic field. From the specific heat data it was stated that the effect of dilution of Mn by non‐magnetic Ga 3+ ions led to reduced Mn magnetic interactions and suppressed the magnetic ordering of Yb in both the 2 a and 4 b positions. Combining the results of all measurements, the magnetic‐field–temperature phase diagram YbMnO 3 was drawn, and the types of the Yb magnetic ordering in both positions were determined.
