Coupled First-Order Transitions In A Fermi-Bose Mixture
K. Sheshadri, A. Chainani
A model of a mixture of spinless fermions and spin-zero hardcore bosons, with filling fractions and , respectively, on a two-dimensional square lattice with {\em composi…
Electronic structure investigation of GdNi using X-ray absorption, magnetic circular dichroism and hard x-ray photoemission spectroscopy
C. W. Chuang, H. J. Lin, F. M. F. de Groot +8
GdNi is a ferrimagnetic material with a Curie temperature Tc = 69 K which exhibits a large magnetocaloric effect, making it useful for magnetic refrigerator applications. We invest…
Nature of the magnetism of iridium in the double perovskite Sr2CoIrO6
S. Agrestini, K. Chen, C. -Y. Kuo +12
We report on our investigation on the magnetism of the iridate double perovskite SrCoIrO, a nominally Ir Van Vleck system. Using x-ray absorption (XAS) a…
Spin-orbit coupling and crystal-field distortions for a low-spin state in BaCoO
Y. Y. Chin, Z. Hu, H. -J. Lin +13
We have studied the electronic structure of BaCoO using soft x-ray absorption spectroscopy at the Co- and O- edges, magnetic circular dichroism at the Co-…
Kondo-induced giant isotropic negative thermal expansion
D. G. Mazzone, M. Dzero, M. Abeykoon +9
Negative thermal expansion is an unusual phenomenon appearing in only a handful of materials, but pursuit and mastery of the phenomenon holds great promise for applications across…
Room temperature large spontaneous exchange bias in hard-soft antiferromagnetic composite BiFeO3-TbMnO3
Prince Kr. Gupta, Surajit Ghosh, Shiv Kumar +12
We report the presence of giant spontaneous exchange bias (HSEB) in a hard and soft antiferromagnetic composite of BiFeO3-TbMnO3 (BFO-TMO in 7:3 and 8:2 ratio). The HSEB varies bet…
