Orbital magnetic moments in FeCr2S4 studied by x-ray magnetic circular dichroism
V. K. Verma, J. Patra, V. R. Singh +8
We have investigated the element specific magnetic characteristics of single-crystal FeCr2S4 using x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD).…
Cr doping-induced ferromagnetism in the spin-glass Cd1-xMnxTe studied by x-ray magnetic circular dichroism
V. K. Verma, S. Sakamoto, K. Ishikawa +7
The prototypical diluted magnetic semiconductor Cd1-xMnxTe is a spin glass (x<0.6) or an antiferromagnet (x>0.6), but becomes ferromagnetic upon doping with a small amount of Cr at…
Electronic States and Possible Origin of the Orbital-Glass State in a Nearly Metallic Spinel Cobalt Vanadate: An X-ray Magnetic Circular Dichroism Study
Yosuke Nonaka, Goro Shibata, Rui Koborinai +8
We have investigated the orbital states of the orbital-glassy (short-range orbital ordered) spinel vanadate CoVO using x-ray absorption spectroscopy (XAS),…
Thickness-dependent magnetic properties and strain-induced orbital magnetic moment in SrRuO3 thin films
K. Ishigami, K. Yoshimatsu, D. Toyota +16
Thin films of the ferromagnetic metal SrRuO3 (SRO) show a varying easy magnetization axis depending on the epitaxial strain and undergo a metal-to-insulator transition with decreas…
Electronic and magnetic properties of off-stoichiometric CoMnSi/MgO interfaces studied by x-ray magnetic circular dichroism
V. R. Singh, V. K. Verma, K. Ishigami +8
We have studied the electronic and magnetic states of Co and Mn atoms at the interface of the CoMnSi (CMS)/MgO (=0.69, 0.99, 1.15 and 1.29) magnetic tunnel junc…
Spectroscopic studies on the electronic and magnetic states of Co-doped perovskite manganite Pr0.8Ca0.2Mn1-yCoyO3 thin films
K. Yoshimatsu, H. Wadati, E. Sakai +13
We have investigated the electronic and magnetic properties of Co-doped Pr0.8Ca0.2MnO3 thin films using various spectroscopic techniques. X-ray absorption and hard x-ray photoemiss…
Thickness-dependent ferromagnetic metal to paramagnetic insulator transition in LaSrMnO thin films studied by x-ray magnetic circular dichroism
Goro Shibata, Kohei Yoshimatsu, Enju Sakai +14
Metallic transition-metal oxides undergo a metal-to-insulator transition (MIT) as the film thickness decreases across a ritical thickness of several monolayers (MLs), but its drivi…
Phase diagram of CaCeMnO thin films studied by X-ray magnetic circular dichroism
T. Harano, G. Shibata, K. Yoshimatsu +14
In the perovskite-type CaCeMnO (CCMO), one can control the transport and magnetic properties through varying Ce content. In the case of thin films, the properti…
Observation of magnetically hard grain boundaries in double-perovskite SrFeMoO
Y. Takahashi, V. K. Verma, G. Shibata +12
Unusual low temperature magneto-resistance (MR) of ferromagnetic SrFeMoO polycrystals has been attributed to magnetically hard grain boundaries which act as spin valves…
