The magnetic anisotropy of antiferroquadrupole (AFQ) phase II and antiferromagnetic (AFM) phase III in Ce0.50La0.50B 6 with a T8 ground state was investigated by ultrasonic measurements. Gama was employed for measurements up to 30 T and a 3He∓4He dilution refrigerator was used for low-temperature experiments down to 20 mK. The phase boundary from paramagnetic phase I to AFQ phase II under [001] magnetic fields closed at H I∓II ∼ 29 t, while under fields along the [110] and [111] directions even up to 30 T , the boundary was still open. The AFM phase III reduced in the fields turning from the [001] to [110] and [111] directions.
