abstract = "An instrument for hard X-ray magnetometry with spatial and time resolutions of 400-ps and sub-2-μm was developed at BL39XU, SPring-8.The technique is based on X-ray magnetic circular dichroism measurements combined with KB focusing mirrors and a fast current source, which generates a pulsed magnetic field of 400-ps duration that is synchronized with the X-ray pulses provided from the storage ring in the 203-bunch operation (42 MHz) with a jitter of 50 ps. By fully using the bulk-sensitivity and element-specificity of hard X-ray dichroism, we have demonstrated that the magnetization reversing process in the nanosecond time scale of the free NiFe and pinned CoFeB/CoFe layers were separated in a 10-μm dot sample with a NiFe/MgO/CoFeB/CoFe/MgO structure mimicking a magnetic tunnel junction device.",
