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 ...
Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems
(1992-03/01)
Motivated by recent work on the critical resistivity of gadolinium, a detailed study has been made of the temperature dependence of the two-point vertex function in the large-momentum regime. The operator-project expansion ...
