Origin of the large positive magnetoresistance in Ge1-xMnx granular thin films
Yuki K. Wakabayashi, Ryota Akiyama, Yukiharu Takeda +9
GeMn granular thin films are a unique and promising material for spintronics applications due to large positive magnetoresistance (MR). Previous studies on GeMn have suggested that…
Electronic Structure of the Ferromagnetic Semiconductor Fe-doped Ge Revealed by Soft X-ray Angle-Resolved Photoemission Spectroscopy
Shoya Sakamoto, Yuki K. Wakabayashi, Yukiharu Takeda +7
GeFe (Ge:Fe) shows ferromagnetic behavior up to a relatively high temperature of 210 K, and hence is a promising material for spintronic applications compatible with…
Volume-wise destruction of the antiferromagnetic Mott insulating state through quantum tuning
Benjamin A. Frandsen, Lian Liu, Sky C. Cheung +25
Metal-to-insulator transitions (MITs) are a dramatic manifestation of strong electron correlations in solids1. The insulating phase can often be suppressed by quantum tuning, i.e.…
