title: Volume Measurements on Chromium to Pressure of 30 Kilobars.
abstract: The unit cell volume of chromium was measured as a function of pressure from 1 bar to 30 kilobars by x-ray diffraction techniques. The antiferromagnetic transition occurred at 1.5 kilobars at 29 degrees C, where there is a discontinuity in the slope of the curve for lattice parameter vs. pressure. By electrical resistance measurements the value of -deltaT(N)/ deltaP was determined to be 5.9 degrees + 0.3 degrees per kilobar. At room temperature chromium remains in the body centered cubic crystal structure from 0 to 55 kilobars.
