Antiferromagnetic spin chain behavior and a transition to 3D magnetic order in Cu(D,L-alanine)2: Roles of H-bonds
Rafael Calvo, Rosana P. Sartoris, Hernan L. Calvo +2
We study the spin chain behavior, a transition to 3D magnetic order and the magnitudes of the exchange interactions for the metal-amino acid complex Cu(D,L-alanine)2.H2O, a model c…
On the ferromagnetic structure of the intermetallic borocarbide TbCo2B2C
M. ElMassalami, R. Moreno, R. M. Saeed +5
Based on magnetization, specific heat, magnetostriction, and neutron diffraction studies on single-crystal TbCo2B2C, it is found out that the paramagnetic properties, down to liqui…
Synthesis and magnetic characterization of TmCo2B2C
M. ElMassalami, R. E. Rapp, F. A. B. Chaves +7
A new quaternary intermetallic borocarbide TmCo2B2C has been synthesized via a rapid-quench of an arc-melted ingot. Elemental and powder-diffraction analyses established its correc…
Magnon Specific Heat of Single Crystal Borocarbides RNi2B2C (R=Tm, Er, Ho, Dy, Tb, Gd)
M. El Massalami, R. E. Rapp, F. A. B. Chaves +2
Zero-field specific heat of the single crystals RNi2B2C (R= Er, Ho, Dy, Tb, Gd) was measured within the temperature range 0.1 K<T<25 K. Linearized spin wave analysis was successful…
Low-temperature specific heat of La0.78Pb0.22MnO3-d manganite
L. Ghivelder, R. S. Freitas, R. E. Rapp +3
The specific heat of the perovskite manganite La0.78Pb0.22MnO3-d was measured from 0.5 to 25 K. The results yield values of the electronic density of states, the Debye temperature,…
Low temperature specific heat of the molecular cluster Fe: contribution of the local field
A. M. Gomes, M. A. Novak, W. C. Nunes +1
We present low temperature specific heat and ac-susceptibility measurements on Fe powdered sample. Below 1.3 K, superparamagnetic blocking effects as well as an excess specif…
