| Outline of Final Research Achievements |
Experimental technique for the low-temperature magnetization measurements with a fine tuning of the field orientation has been developed. Using this technique, we studied a field-induced quantum phase transition of the itinerant Ising ferromagnet URhGe and obtained the detailed structure of the wing phase diagram below the tricritical point. We also examined the liquid-gas transition of spin ice Dy2Ti2O7 in a magnetic field by precisely tuning the field direction along the [111] axis. We confirmed that the first-order transition occurring near 0.9T has an intrinsic width of about 0.5T even at very low temperatures. The results suggest the presence of some spatial structure in the monopole crystallization transition.
