Gigantic magnetoelectric effect caused by magnetic-field-induced canted antiferromagnetic-paramagnetic transition in quasi-two-dimensional CaCoSiO crystal
M. Akaki, J. Tozawa, D. Akahoshi +1
We have investigated the magnetic and dielectric properties of CaCoSiO crystal. The dielectricity and magnetism of CaCoSiO are strongly coupled below a cant…
Critical exponent for the quantum Hall transition
Keith Slevin, Tomi Ohtsuki
We report an estimate of the critical exponent of the Chalker-Coddington model of the integer quantum Hall effect that is significantly larger than p…
Point-Contact Conductance in Asymmetric Chalker-Coddington Network Model
Koji Kobayashi, Tomi Ohtsuki, Keith Slevin
We study the transport properties of disordered two-dimensional electron systems with a perfectly conducting channel. We introduce an asymmetric Chalker-Coddington network model an…
Analytical Study on the Sunyaev-Zeldovich Effect for Clusters of Galaxies
Satoshi Nozawa, Yasuharu Kohyama
Starting from a covariant formalism of the Sunyaev-Zeldovich effect for the thermal and non-thermal distributions, we derive the frequency redistribution function identical to Wrig…
Cr-doping effect on the orbital fluctuation of heavily doped Nd1-xSrxMnO3 (x ~ 0.625)
R. Tasaki, S. Fukushima, M. Akaki +2
We have investigated the Cr-doping effect of Nd0.375Sr0.625MnO3 near the phase boundary between the x2-y2 and 3z2-r2 orbital ordered states, where a ferromagnetic correlation and c…
Persistent and Reversible Phase Control in GdMnO near the Phase Boundary
H. Kuwahara, M. Akaki, J. Tozawa +3
We have investigated temperature and magnetic-field dependence of dielectric properties in the orthorhombic GdMnO single crystal which is located near the phase boundary betwee…
