Asymmetric quintuplet condensation in the frustrated S=1 spin dimer compound Ba3Mn2O8
E. C. Samulon, Y. Kohama, R. D. McDonald +5
Ba3Mn2O8 is a spin-dimer compound based on pairs of S = 1, 3d2, Mn5+ ions arranged on a triangular lattice. Antiferromagnetic intradimer exchange leads to a singlet ground state in…
Bose-Einstein Condensation of Triplons in Ba3Cr2O8
A. A. Aczel, Y. Kohama, M. Jaime +5
By performing heat capacity, magnetocaloric effect, torque magnetometry and force magnetometry measurements up to 33 T, we have mapped out the T-H phase diagram of the S = 1/2 spin…
Psuedo-isotropic upper critical field in cobalt-doped SrFe2As2 epitaxial films
S. A. Baily, Y. Kohama, H. Hiramatsu +4
The temperature and angular dependence of the upper critical field (Hc2) is reported for cobalt-doped SrFe2As2 epitaxial films between Tc and 0.5 K in pulsed magnetic fields up to…
Hall coefficient and Hc2 in underdoped LaFeAsO0.95F0.05
Y. Kohama, Y. Kamihara, S. Riggs +5
The electrical resistivity and Hall coefficient of LaFeAsO0.95F0.05 polycrystalline samples were measured in pulsed magnetic fields up to m0H = 60 T from room temperature to 1.5 K.…
Ferromagnetic spin fluctuation in LaFeAsO1-xFx
Yoshimitsu Kohama, Yoichi Kamihara, Masahiro Hirano +3
The F doped LaFeAsO, a recently discovered superconductor with the high Tc of 26 K, has been studied by the resistivity, magnetic susceptibility, and heat capacity measurements in…
