We investigated the phase-transition kinetics of magnetic skyrmion lattice (SkL) in MnSi by means of stroboscopic small-angle neutron scattering (SANS). Temporal evolutions of SANS patterns were measured with time resolution of 13 ms while sweeping temperature as fast as 50 Ks$$^{-1}$$. It turned out that the paramagnetic-to-SkL transition immediately occurs upon traversing the equilibrium phase boundary on the rapid cooling, whereas the SkL-to-conical transition can be kinetically avoided to realize the low-temperature metastable SkL with a long-range magnetic order. The formation of the metastable SkL was found to be strongly dependent not only on cooling rate, but also on magnetic eld and trajectory in the H-T phase diagram.

The magnetic phase diagrams for $$R$$VO$$_{3}$$ ($$R$$ = Y, Tb) were determined by low temperature and high pressure neutron-diffraction techniques. We found that the magnetic ground state in TbVO$$_{3}$$ changes from ${it C}$-type spin ordering (${it C}$-SO) to ${it G}$-type spin ordering (${it G}$-SO) on application of pressure. The transition of the magnetic ground state also indicates that the ground state of the orbital ordering changes from ${it G}$-type orbital ordering (${it G}$-OO) to ${it C}$-type orbital ordering (${it C}$-OO). In YVO$$_{3}$$, the ${it G}$-SO and ${it C}$-OO phases set in simultaneously up to 6.2 GPa, and the disorder-[${it G}$-SO, ${it C}$-OO] phase transition appears above 6 GPa. This is the first observation of a simultaneous spin and orbital order-disorder phase transition in perovskite-type transition-metal oxides $$R$$MO$$_{3}$$. The [${it G}$-SO, ${it C}$-OO] phase is strongly stabilized with increasing pressure, and both the covalency effect and the superexchange interaction play roles in this stabilization.

The complex phase transition of the magnetic long-range order in Fe$$_{0.7}$$Co$$_{0.3}$$Si has been investigated by small-angle neutron scattering (SANS) measurement at low temperatures under an external magnetic field. A variety of scattering patterns, such as ring, crescent-shaped, and diffusive spots, were observed by changing temperature and applying a magnetic field. The results could be interpreted by an analogy of the phase transition of the liquid crystal when the net magnetization is regarded as the director of the liquid crystal.
