Notes:
With a newly built superconducting quantum interference device magnetometer, the time range of measurements of the thermoremanent magnetization (TRM) was extended to less than 10 ms. This new method allows a direct investigation of aging and relaxation in the spin glass region for short times. As a first example for fast TRM, the magnetization in a single crystal of the insulating spin glass CsNiFeF6 was measured in the time range −2〈log(t/s)〈3 at magnetic fields between 2 and 20 G at temperatures between 4.7 and 1.7 K. Additionally, the zero field and field cooled magnetization of this sample to temperatures up to 9 K was studied.
