内容記述 | We have been developing a high resolution MRI (Magnetic Resonance Imaging), 'MRI Microscope', by exploiting a high magnetic field and ultra low temperature environment. By using the MRI Microscope, it will be possible to check critical Casimir effect on the contact angle of the interface of phase-separated He-3 and He-4 mixtures. At mK-temperature, we took MRI pictures at a magnetic field of 0.92 T and magnetic field gradient of 0.5 T/m. We could improve MRI resolution in two-Dimensional pictures to 6 microns by 6 microns. In order to visualize a contact line region of the mixtures with much higher resolution, we prepared a new sample cell. We performed MRI using the new cell at a magnetic field of 7 T and magnetic field gradient of 1.6 T/m. | |||||
