Fig. 5

T-p-H phase diagram of LaCrGe₃. Red solid lines are the second order phase transition and blue color planes are planes of first order transitions. Green color areas represent the AFM _Q and AFM _Q′ phases. For clarity, only data points at 2 K and along the transitions lines are shown. Black circles indicate the paramagnetic (PM)-ferromagnetic (FM) transition. Black squares indicate the wing critical line for FM1 and empty squares indicate the wing critical line for FM2. Blue diamonds indicate the first order transition to the FM1 state at 2 K and empty diamonds, the first order transition to FM2 at 2 K. Empty triangles indicate the PM-modulated magnetic phase (AFM _Q ) and “+” indicate the AFM _Q′ boundary. “×” indicate the AFM _Q or AFM _Q′ boundary at 2 K. The full set of data points can be found in Supplementary Note 3. For clarity, the green surfaces representing the boundaries for the AFM _Q or AFM _Q′ phases are shown only in the region of positive magnetic field
