Local Tunneling Spectroscopy across a Metamagnetic Critical Point in the Bi-layer Ruthenate Sr3Ru2O7

K. Iwaya, S. Satow, T. Hanaguri +8

The local spectroscopic signatures of metamagnetic criticality in Sr3Ru2O7 were explored using scanning tunneling microscopy (STM). Singular features in the tunneling spectrum were…

Logarithmic growth law in the two-dimensional Ising spin glass state resulting from the electron doping in single-layered manganites

R. Mathieu, J. P. He, Y. Kaneko +3

The ac-susceptibility of the electron doped single-layered manganite La $_{1.1}$ Sr $_{0.9}$ MnO $_{4}$ is analyzed in detail. A quasi two-dimensional (2 $D$ ) antiferromagnetic (AFM) order…

Variation of charge/orbital ordering in layered manganites Pr1-xCa1+xMnO4 investigated by transmission electron microscopy

X. Z. Yu, R. Mathieu, T. Arima +9

Structural features of the charge/orbital ordering (CO/OO) in single-layered manganites Pr1-xCa1+xMnO4 have been investigated systematically by transmission electron microscopy. An…

Coexistence of long-ranged charge and orbital order and spin-glass state in single-layered manganites with weak quenched disorder

R. Mathieu, J. P. He, X. Z. Yu +6

The relationship between orbital and spin degrees of freedom in the single-crystals of the hole-doped Pr $_{1 - x}$ Ca $_{1 + x}$ MnO $_{4}$ , 0.3 $\leq$ $x$ $\leq$ 0.7, has been investigated…
