| Outline of Final Research Achievements |
We have fabricated artificial superlattices using heavy-fermion compounds and controlled electronic state by electric-field-effect to search novel superconducting and topological phenomena. In heavy-fermion superlattices, we have demonstrated (1) artificial creation of superconductor with broken inversion symmetry, (2) realization of extremely strong-coupling superconductivity in hybrid superlattices comprised of an antiferromagnet and a superconductor, and (3) dimensional control of antiferromagnetism. Also, we have discovered a metallic state induced by weak magnetic field and an Ising superconducting state where spins of paired electrons are polarized perpendicular to the two-dimensional planes.
