Experimental Phase Diagram and Dynamics of a Dilute Dipolar-Coupled Ising System

J. A. Quilliam, S. Meng, J. B. Kycia

We present ac susceptibility and specific heat measurements taken on samples of LiHo${}_x$Y${}_{1-x}$F${}_4$ in the dilute limit: x = 0.018, 0.045, 0.080 and 0.12. Susceptibility measure…
