Heat capacity of gadolinium near the Curie temperature
(1993-06/01)
High-resolution AC calorimetric data near the Curie point are reported for several single crystals of gadolinium. The critical temperature and the shape of the heat-capacity curve near Tc both depend on the sample-preparation ...
Critical behavior of two-dimensional magnetic systems with dipole-dipole interactions
(1989-01/01)
The critical exponents of two-dimensional dipolar magnetic systems with isotropic in-plane ordering may be obtained from the expansion which determines the exponents of isotropic three-dimensional dipolar systems. However, ...
Photoacoustic investigation of the temperature and magnetic-field dependence of the specific-heat capacity and thermal conductivity near the Curie point of gadolinium
(1995-11/01)
The photoacoustic technique was used as a simple but accurate tool to simultaneously determine the specific-heat capacity C and thermal conductivity K of gadolinium in the neighborhood of the Curie point. One polycrystalline ...
Critical magnetic susceptibility of gadolinium
(1988-08/01)
The magnetic suspectibility of a single crystal of high-purity gadolinium has been measured in the critical region with use of AC susceptibility methods. For reduced temperatures t10-3, the data are described by a simple ...
Anisotropy of the critical magnetic susceptibility of gadolinium
(1989-06/05)
The magnetic susceptibility along the c axis (xc) and in the basal plane (xb) has been measured on a single crystal of Gd in the reduced temperature range 410-4t1.310-2. Uniaxial anisotropy is observed. Magnetic dipole-dipole ...
Dipole-dipole interactions and the critical resistivity of gadolinium
(1987-06/01)
Results are presented for the electrical resistivity of a c-axis single crystal of high-purity gadolinium metal in the immediate vicinity of the Curie temperature. Numerical analysis reveals that the data are not well ...
Lattice sums for dipolar systems
(1987-12/01)
A general method for the evaluation of lattice sums determining the effective parameters in the Hamiltonian of a dipolar magnetic system is described. The anisotropy of the Hamiltonian is examined for crystal structures ...
