Report

Study of superconductivity of very thin $\mathrm{FeSe}_{1-x}\mathrm{Te}_x$ films investigated by microwave complex conductivity measurements

Autor: Matsumoto, Gaku, Ogawa, Ryo, Higasa, Koji, Kobayashi, Tomoki, Nakagawa, Hiroki, Maeda, Atsutaka

Complex conductivity measurements spanning the entire temperature range, including the vicinity of $T_c$, were conducted on systematically varied FeSe$_{1-x}$Te$_x$ ($x$ = 0 - 0.5) very thin films. By applying a novel cavity measurement technique emp

In this study, we grow FeSe/SrTiO$_{3}$ with thicknesses of 4-19 nm using pulsed laser deposition and investigate their magneto-transport properties. The thinnest film (4 nm) exhibit negative Hall effect, indicating electron transfer into FeSe from t

A Neural Network Model of the Entorhinal Cortex and Hippocampus for Event-order Memory Processing

Autor: Nakagawa, Hiroki, Tateno, Katsumi, Takada, Kensuke, Morie, Takashi

To solve a navigation task based on experiences, we need a mechanism to associate places with objects and to recall them along the course of action. In a reward-oriented task, if the route to a reward location is simulated in mind after experiencing
