Thermally quenched metastable phase in the Ising model with competing interactions
Hiroshi Oike, Hidemaro Suwa, Yasunori Takahashi +1
Thermal quenching has been used to find metastable materials such as hard steels and metallic glasses. More recently, quenching-based phase control has been applied to correlated e…
Low-temperature hysteresis broadening emerging from domain-wall creep dynamics in a two-phase competing system
Keisuke Matsuura, Yo Nishizawa, Yuto Kinoshita +6
Hysteretic behaviour accompanies any first-order phase transition, forming a basis for many applications. However, its quantitative understanding remains challenging, and even a qu…
Thermodynamic determination of the equilibrium first-order phase-transition line hidden by hysteresis in a phase diagram
Keisuke Matsuura, Yo Nishizawa, Markus Kriener +4
Phase diagrams form the basis for the study of material science, and the profiles of phase-transition lines separating different thermodynamic phases include comprehensive informat…
Kinetic approach to superconductivity hidden behind a competing order
H. Oike, M. Kamitani, Y. Tokura +1
Exploration for superconductivity is one of the research frontiers in condensed matter physics. In strongly correlated electron systems, the emergence of superconductivity is often…
Topological stability versus thermal agitation in a metastable magnetic skyrmion lattice
H. Oike, A. Kikkawa, N. Kanazawa +4
Topologically stable matters can have a long lifetime, even if thermodynamically costly, when the thermal agitation is sufficiently low. A magnetic skyrmion lattice (SkL) represent…
Mottness in a doped organic superconductor
H. Oike, K. Miyagawa, H. Taniguchi +1
We report the pressure study of a doped organic superconductor with Hall coefficient and conductivity measurements. We find that maximally enhanced superconductivity and a non-Ferm…
