Abstract
We report Hall sensor measurements of the magnetic relaxation of Mn-12-acet ate as a function of magnetic field applied along the easy axis of magnetiz ation. Data taken at a series of closely spaced temperatures between 0.24 a nd 1.9 K provide new clues for understanding the physics of quantum tunneli ng of magnetization in Mn-12-acetate.
