Elastic neutron diffraction experiments performed at H=0 on a powdered specimen of LiZn0.5Mn1.5O4 have shown that this compound is a ferromagnet up to TC =22 K with a reduced moment σ(1.4 K)=2.04 μB to be compared to the expected σ0=3 μB for the

Magnetic structures are studied in the case of a Bravais lattice when biquadratic interactions jS 4 exist in addition to the bilinear ones JS 2 between first and second nearest neighbours. Modes coupling is found to occur even at small jS 2 / J ratio

Elastic neutron diffraction experiments show that the cubic spinel LiZn 0.5 Mn 1.5 0 4 which has an O 7 space group is a ferromagnet up to T c = 22K where the moment drops from 1.1 μ B to zero. Another first order magnetic transition takes place at

High magnetic field measurements indicate that LiZn0.5Mn1.5O4 which is a ferromagnet with Tc = 38.5 K develops only 72% of the expected moment length for Mn4+ ion. This result is confirmed by neutron diffraction experiments which also show that this

Neutron diffraction and magnetization measurements performed on both sides of TN = 13 K on Ag12In12Cr2S4 are respectively, explained by an helimagnetic macrodomain phase at T < TN and a microdomain sinusoidal phase at TN < T < T1 (T1 = 43 K). At T1 <
