✦ Synopsis

A generalization of the Skocpol-Beasley-Tinkham hotspot theory to include an approximate temperature dependence of the conductive heat transfer term of the heat flow equations clearly indicates that the role of the thermal conductivity of the material of the film is not reflected in the observed temperature dependence of the minimum current In required to sustain a hotspot in a long, thin-film superconductor. This observation leads to the derivation of a simplified expression for Ih valid for a wider range of bath temperatures.

## Abstract An anisotropic magnetic thin film is considered with atomic spins, __S__, arranged in a lattice with inversion symmetry and arbitrary surface orientation. The Hamiltonian of the system contains the Zeeman term, the Heisenberg exchange term, and a term for the uniaxial volume anisotropy
