Phase diagram of the spin configuration accompanied with different crystal structures for compounds ( denotes the easy magnetization direction and PS denotes the paramagnetic state).
(a) Magnetization curves for compounds. The inset of (a) show the magnetic field dependence of the magnetization range from 0 kOe to 6 kOe and the absolute values of magnetocrystalline anisotropy constant K1 at room temperature; (b) dM/dH versus at high fields for different Tb content.
Composition dependence of the ratio for the compounds.
Magnetization in the cubic coordinate system and different monoclinic magnetization paths. T, R, and O represent magnetization direction of  (tetragonal),  (rhombohedral), and  (orthorhombic), respectively. [MRT ] and [MRO ] describe magnetization rotation paths of - and -, respectively.
The tridimensional representation of free energy for compound. Full dots represent positions of equilibrium rhombohedral (R), and metastable Orthorhombic (O), tetragonal (T), and cubic (C) phases at room temperature. The dashed lines are the profiles along different magnetization paths: [M RR ], [M RT ], and [M RO ].
