Transition ferromagnetic

Welp U, Fleshier S, Kwok WK, Crabtree GW, Carlson KD, Wang HH, Geiser U, Williams JM, Hitsman VM (1992) Weak ferromagnetism in k-(ET)2Cu[N(CN)2]C1, where (ET) is bis (ethylenedithio)tetrathiafulvalene. Phys Rev Lett 69 840-843. This paper mistakenly described that the AF transition occurred at 45 K and weak ferromagnetic transition at 23 K. The magnetic susceptibility measurements could not identify the transition either AF or SDW... 

For the size determination of spin polarons from the field-dependent magnetization data (SQUID results in Fig. 6) we first employed a fitting based on the Brillouin function /3(./), which is justified since the respective temperatures around T]T are sufficiently above the ferromagnetic transition. The paramagnetic magnetization as a function of field is given by... 

Ce3Cu3Sb4 was found to be a semiconducting ferromagnet with ferromagnetic transition temperature, Tm = 10 T while GdTTitSh4 was reported to be a metallic antiferromagnet with 7n = 12K(Patil et al., 1996).

We have measured the frequency-field dependence of the ESR signal between 30 MHz and 245 GHz. At high fields (Fig. 20) this relation is nearly linear at T=5 K, i.e., well below the ferromagnetic transition temperature [105]. This may be at first glance surprising, as in the magnetically ordered phase one would expect a nonlinear resonance field-resonance frequency relation. The answer to that came only later on from low-field ferromagnetic resonance data discussed in the next section. 

In the present problem the imperfect bifurcation theory results in clarifying the close analogy of the development of polarity in Fucus with a ferromagnetic transition. To demonstrate this we multiply (kk) by e3 and let ge s m, aX e2 s t and bE e3 = h. Then (kk) becomes 2 3...
