The in-plane ferromagnetic ordering in half-metallic CuCr2 Se4−x Brx (x = 0.25) single crystal

The two-dimensional (2D) isothermal EPR spectra at T = 380 K in the ferromagnetic phase (the red color corresponds to the high intensity while the blue to the low). The top-left inset shows the measurement style, while the top-right inset plots the g-factor as a function of the rotation angle φ (the solid curve is fitted).200
