Thickness-dependent ferromagnetic metal to paramagnetic insulator transition in La 0.6 Sr 0.4 MnO 3 thin films studied by x-ray magnetic circular dichroism
Goro Shibata,K. Yoshimatsu,Enju Sakai,Enju Sakai,V. R. Singh,Virendra Kumar Verma,K. Ishigami,T. Harano,T. Kadono,Yukiharu Takeda,Tetsuo Okane,Yuichi Saitoh,Hiroshi Yamagami,Hiroshi Yamagami,Akihito Sawa,Hiroshi Kumigashira,Hiroshi Kumigashira,M. Oshima,Tsuneharu Koide,A. Fujimori,A. Fujimori +20 more
TL;DR: In this paper, the authors studied the thickness-dependent metal-to-insulator transition (MIT) of the ferromagnetic metal and found that as the film thickness decreased across a critical thickness of several monolayers (MLs), a gradual decrease of the Ferromagnetic signals and a concomitant increase of paramagnetic signals were observed, while the Mn valence abruptly decreased towards

Photoemission and x-ray absorption studies of the isostructural to Fe-based superconductors diluted magnetic semiconductor Ba 1 − x K x ( Zn 1 − y Mn y ) 2 As 2
H. Suzuki,Kan Zhao,Goro Shibata,Youtarou Takahashi,Shoya Sakamoto,K. Yoshimatsu,Bijuan Chen,Hiroshi Kumigashira,F.-H. Chang,Hong-Ji Lin,D. J. Huang,Chien-Te Chen,Bo Gu,Sadamichi Maekawa,Yasutomo J. Uemura,Chiming Jin,A. Fujimori +16 more
TL;DR: In this paper, a diluted magnetic semiconductor with the same crystal structure as the iron-based superconductor BaFe has been shown to exhibit ferromagnetic transition temperatures as high as 230 K, which is an ideal framework for high-temperature superconductivity and for ferromagnetism.
