Fluctuation theorem for spin transport at insulating ferromagnetic junctions
Tetsuya Sato, Masahiro Tatsuno, Mamoru Matsuo +1
General relations for nonequilibrium spin transport at a magnetic junction between a normal metal and a ferromagnetic insulator are derived from the quantum fluctuation theorem. Th…
Appearance of ferromagnetism in Pt(100) ultrathin films originated from quantum-well states
Tatsuru Yamada, Keisuke Ochiai, Hirofumi Kinoshita +5
Ferromagnetism was observed in a Pt(100) ultrathin film deposited on a SrTiO3(100) substrate. The ferromagnetism, which appears in films with thicknesses of 2.2-4.4 nm, periodicall…
Switching of magnetism via modifying phase shift of quantum-well states by tailoring the interface electronic structure
Shunsuke Sakuragi, Hiroyuki Kageshima, Tetsuya Sato
We demonstrate control of the magnetism of Pd(100) ultrathin films, which show d-electron quantum-well induced ferromagnetism, via modulation of the interface electronic state usin…
Manipulation of magnetization in Pd(100) ultrathin films with quantum well structure using modification of Schottky barrier potentials
Hidetake Tanabe, Shunsuke Sakuragi, Tetsuya Sato
The magnetization of Pd(100) ultrathin films that show ferromagnetism due to quantum well states was manipulated by changing the quantum well state with an applied bias voltage. Th…
Spontaneous Distortion and Ferromagnetism Induced by Quantum-well States in Pd(100) Ultrathin Films
Shunsuke Sakuragi, Hiroo Tajiri, Hiroyuki Kageshima +1
We study the crystal structure of Pd(100) ultrathin films, which show ferromagnetism induced by the quantum confinement effect, using in-situ X-ray crystal truncation rod measureme…
Effect of the change in the interface structure of Pd(100)/SrTiO3 for quantum-well induced ferromagnetism
Shunsuke Sakuragi, Tomoyuki Ogawa, Tetsuya Sato
Pd(100) ultrathin films show ferromagnetism induced by the confinement of electrons in the film, i.e., the quantum-well mechanism. In this study, we investigate the effect of the c…
Aging behavior of spin glasses under bond and temperature perturbations from laser illumination
Ryuta Arai, katsuyoshi komatsu, Tetsuya Sato
We have studied the nonequilibrium dynamics of spin glasses subjected to bond perturbation, which was based on the direct change in the spin-spin interaction , using photo illu…
