A magnetization measurement system has been developed for extremely small samples in a diamond-anvil cell (DAC). The system is basically a vibrating coil magnetometer, and a SQUID is used for high sensitive detection of the gradient of the magnetic flux. The system enables one to make magnetization measurements at pressures up to about 15 GPa in the temperature range from 1. 4 to 60 K. Magnetization changes as small as 10<SUP>-9</SUP>-10<SUP>-10</SUP> emu can be detected if the temperature is limited to the range from 5 to 20K. The performance of the system is illustrated by magnetization measurements of EuTe at pressures up to about 12 GPa.
