The thermal expansion of Ni-Cr alloys, near the critical concentration xy at which ferromagnetic order appears, shows a small characteristic anomaly below about 10 K. This anomaly increases in size as X, is approached, then abruptly changes sign going through x,. We deduce from the expansion data th
