The specific heat, magnetization, and magnetocapacitance of YbMnO3 and YbMn0.7Ga0.3O3 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 Ga3+ ions led to reduced Mn magnetic interactions and suppressed the magnetic ordering of Yb in both the 2a and 4b positions. Combining the results of all measurements, the magnetic-field-temperature phase diagram YbMnO3 was drawn, and the types of the Yb magnetic ordering in both positions were determined.
