Oscillatory magnetostriction of LaB6 and PrB6 single crystals was observed. The de Haas van Alphen frequencies in LaB 6 range from the order of 104 to 107 gauss and were related to the interconnecting neck orbit between spherical ellipsoids. In PrB6, only one de Haas van Alphen frequency of 1.4 x 106 gauss was observed. Both results agreed well with the conventional de Haas van Alphen measurement but did not agree with the acoustic measurement.
