Excitation spectrum and low-temperature magnetism in disordered defect-fluorite Ho2Zr2O7
P. L. Oliveira Silva, J. G. A. Ramon, Viviane Peçanha-Antonio +4
In this work, we report on the thermomagnetic characterization and crystalline-electric field (CEF) energy scheme of the disordered defect-fluorite Ho2Zr2O7. This structural phase…
Melting of Spin Ice state through structural disorder in Dy2Zr2O7
J. G. A. Ramon, C. W. Wang, L. Ishida +5
Neutron scattering, a.c. magnetic susceptibility and specific heat studies have been carried out on polycrystalline Dy2Zr2O7. Unlike the pyrochlore spin ice Dy2Ti2O7, Dy2Zr2O7 crys…
Crossover from one- to three-dimensional behavior in the S = 1/2 Heisenberg antiferromagnet Cu(N2H5)2(SO4)2
A. Paduan-Filho, A. P. Vieira, J. G. A. Ramon +1
From experimental and theoretical analyses of magnetic and specific-heat properties, we present the complete magnetic phase diagram of the quasi-one-dimensional antiferromagnet Cu(…
