Ferrimagnetism Induced by Off-Site Coulomb Interaction in an Itinerant Electron System

Hirohito Aizawa

Motivated by weak ferromagnetism (FM) in a $τ$ -type molecular conductor ( $τ$ -MC), we examine its mechanism using a two-band extended Hubbard model. Applying the random phase approx…

Electronic Structure Calculation and Superconductivity in $λ$ -(BETS) $_{2}$ GaCl $_{4}$

Hirohito Aizawa, Takashi Koretsune, Kazuhiko Kuroki +1

Quasi-two-dimensional molecular conductor $λ$ -(BETS) $_{2}$ GaCl $_{4}$ shows superconductivity (SC) below 5.5K, neighboring the dimer-type Mott insulating phase. To elucidate the origin…

Microscopic theory of a superconducting gap in the quasi-one-dimensional organic conductor (TMTSF) $_{2}$ ClO $_{4}$ : Model derivation and two-particle self-consistent analysis

Hirohito Aizawa, Kazuhiko Kuroki

We present a first-principles band calculation for the quasi-one-dimensional (Q1D) organic superconductor (TMTSF) $_{2}$ ClO $_{4}$ . An effective tight-binding model with the TMTSF molecu…
