Deterministic influence of substrate-induced oxygen vacancy diffusion on thin film growth
Saikat Das, Tadakatsu Ohkubo, Shinya Kasai +1
In oxide epitaxy, the growth temperature and background oxygen partial pressure are considered as the most critical factors that control the phase stability of an oxide thin film.…
Exceeding 400% tunnel magnetoresistance at room temperature in epitaxial Fe/MgO/Fe(001) spin-valve-type magnetic tunnel junctions
Thomas Scheike, Qingyi Xiang, Zhenchao Wen +4
Giant tunnel magnetoresistance (TMR) ratios of 417% at room temperature (RT) and 914% at 3 K were demonstrated in epitaxial Fe/MgO/Fe(001) exchanged-biased spin-valve magnetic tunn…
Transient response of spin Peltier effect revealed by lock-in thermoreflectance measurement
Takumi Yamazaki, Ryo Iguchi, Tadakatsu Ohkubo +2
Transient response of the spin Peltier effect (SPE) in a Pt/yttrium iron garnet junction system has been investigated by means of a lock-in thermoreflectance method. We applied an…
Searching the weakest link: Demagnetizing fields and magnetization reversal in permanent magnets
J. Fischbacher, A. Kovacs, L. Exl J. Kühnel +5
Magnetization reversal in permanent magnets occurs by the nucleation and expansion of reversed domains. Micromagnetic theory offers the possibility to localize the spots within the…
Growth and characterization of n-type electron-induced ferromagnetic semiconductor (In,Fe)As
Pham Nam Hai, Le Duc Anh, Shyam Mohan +5
We show that by introducing isoelectronic iron (Fe) magnetic impurities and Beryllium (Be) double-donor atoms into InAs, it is possible to grow a n-type ferromagnetic semiconductor…
