| Outline of Final Research Achievements |
In the convectional magnets, the magnetic properties carried by spins and electric properties carried by orbitals of electrons are often separated. In recent condensed matter physics, physical properties of new type of magnets, where the spins and orbitals are strongly coupled, are investigated intensively. We aim to discover novel magnetism and uncover the magnetic properties of spin-orbital coupled magnets by the synthesis of new materials and physical properties measurements in strong pulsed magnetic field.
We discovered novel magnetic phenomena such as the phase transition into the robust nonmagnetic ground state, changes of the effect of the spin-orbit coupling depending on the type of halogen ions, and the magnetic field induced phase transition.
