Abstract (EN): We present the magnetic phase diagram of TbMn1-xFexO3 substitutional solid solutions in the whole concentration range 0 <= x <= 1 as determined from magnetization and specific-heat measurements and as supported by already known magnetic structures published on this substitutional system. We have found that the dominant magnetic ion in the concentration range 0 <= x <= 0.2 is Mn, while Fe ions do not create an independent magnetic structure, but strongly affect the magnetic properties of the parent compound by suppressing the magnetic-ordering temperature as well as the magnetic order-order transition to a cycloidal phase. The magnetism in the concentration range 0.2 <= x <= 1 is driven by the Fe sublattice. The Mn ions again do not order in a long-range magnetic ordered state, but stabilize five magnetic phases of the Fe sublattice above 2 K. Magnetic ordering of the Tb sublattice is observed at temperatures below 8.2 K over entire concentration range.
