Antiferromagnetism of Zn1−xGa2x3Cr2Se4 (for 0.0⩽x⩽0.5)+

Structural and magnetic properties of single-crystalline spinel systems ZnCr2−xAlxSe4 (x=0.15 and 0.23)

“…[12][13][14], yet similar to that quoted in Ref. [20]. The magnetic susceptibility anomalies at T N are very sharp in agreement with the early reports for the latter spinel (see e.g.…”

“…3. As seen, at 4.2 K the magnetization in the two compounds abruptly flattens above 7 T. The saturation magnetic moment amounts to 2.50 (1) [20]. Apparently, with rising x in the ZnCr 2−x Al x Se 4 system there occurs a rapid reduction in the magnitude of the magnetic moment calculated per one chromium atom.…”

Correlation between the electric and conical‐uniaxial ferromagnetic phase transitions in the metallic spinel CuCr2Se4

“…The canted arrangement of the ferrimagnetic state is considered to be a conical state in CuCr 2 Se 4 . Krok et al [14] deduced from the magnetization measurements that the conicalferromagnetic phase transition occurs at x ≈ 0.8 of Cu x Zn 1-x Cr 2 Se 4 . However, we consider that the conical spin order exists below T 1 (about 70 K, 70 K, 68 K and 66 K at H = 50 G, 400 G, 800 G and 0.2 T, respectively) in CuCr 2 Se 4 .…”

Magnetic properties of the Fe 2−x 3+ Fe x 2+ V4−x Mo x O13 phase type

“…On the other hand, deflection of the curve, a = f(B) at an applied field of ,-~ 13 T suggests that a strong magnetic field involves the formation 6f a conical spin structure. Formation of such structures at strong magnetic fields was observed in the chromium spinels [17,18]. Existence of the spin cone in the sample under investigation is indicated by the a = f(T) curve shape (Fig.…”
